LIM is a small protein-protein interaction domain, containing two zinc fingers; LIM domains are identified in a diverse group of proteins with wide variety of biological functions, including gene expression regulation, cell fate determination, cytoskeleton organization, tumor formation and development. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein complexes. They perform their functions through interactions with other protein partners. LIM domains are 50-60 amino acids in size and share two characteristic highly conserved zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. The consensus sequence of LIM domain has been defined as C-x(2)-C-x(16,23)-H-x(2)-[CH]-x(2)-C-x(2)-C-x(16,21)-C-x(2,3)-[CHD] (where X denotes any amino acid).

The first LIM domain of Enigma-like family; The first LIM domain of Enigma-like family: The Enigma LIM domain family is comprised of three members: Enigma, ENH, and Cypher (mouse)/ZASP (human). These subfamily members contain a single PDZ domain at the N-terminus and three LIM domains at the C-terminus. Enigma was initially characterized in humans and is expressed in multiple tissues, such as skeletal muscle, heart, bone, and brain. The third LIM domain specifically interacts with the insulin receptor and the second LIM domain interacts with the receptor tyrosine kinase Ret and the adaptor protein APS. Thus Enigma is implicated in signal transduction processes, such as mitogenic activity, insulin related actin organization, and glucose metabolism. The second member, ENH protein, was first identified in rat brain. It has been shown that ENH interacts with protein kinase D1 (PKD1) via its LIM domains and forms a complex with PKD1 and the alpha1C subunit of cardiac L-type voltage-gated calcium channel in rat neonatal cardiomyocytes. The N-terminal PDZ domain interacts with alpha-actinin at the Z-line. ZASP/Cypher is required for maintenance of Z-line structure during muscle contraction, but not required for Z-line assembly. In heart, Cypher/ZASP plays a structural role through its interaction with cytoskeletal Z-line proteins. In addition, there is increasing evidence that Cypher/ZASP also performs signaling functions. Studies reveal that Cypher/ZASP interacts with and directs PKC to the Z-line, where PKC phosphorylates downstream signaling targets. LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms.

The first LIM domain of the paxillin like protein family; The first LIM domain of the paxillin like protein family: This family consists of paxillin, leupaxin, Hic-5 (ARA55), and other related proteins. There are four LIM domains in the C-terminal of the proteins and leucine-rich LD-motifs in the N-terminal region. Members of this family are adaptor proteins to recruit key components of signal-transduction machinery to specific sub-cellular locations. Paxillin is found at the interface between the plasma membrane and the actin cytoskeleton. Paxillin serves as a platform for the recruitment of numerous regulatory and structural proteins that together control the dynamic changes in cell adhesion, cytoskeletal reorganization and gene expression that are necessary for cell migration and survival. Leupaxin is a cytoskeleton adaptor protein, which is preferentially expressed in hematopoietic cells. It associates with focal adhesion kinases PYK2 and pp125FAK and identified to be a component of the osteoclast pososomal signaling complex. Hic-5 controls cell proliferation, migration and senescence by functioning as coactivator for steroid receptors such as androgen receptor, glucocorticoid receptor and progesterone receptor.

The C-terminal region of paxillin contains four LIM domains which target paxillin to focal adhesions, presumably through a direct association with the cytoplasmic tail of beta-integrin. The N-terminal of paxillin is leucine-rich LD-motifs. Paxillin is found at the interface between the plasma membrane and the actin cytoskeleton. The binding partners of paxillin are diverse and include protein tyrosine kinases, such as Src and FAK, structural proteins, such as vinculin and actopaxin, and regulators of actin organization. Paxillin recruits these proteins to their function sites to control the dynamic changes in cell adhesion, cytoskeletal reorganization and gene expression.

The first LIM domain of Leupaxin; The first LIM domain of Leupaxin: Leupaxin is a cytoskeleton adaptor protein, which is preferentially expressed in hematopoietic cells. Leupaxin belongs to the paxillin focal adhesion protein family. Same as other members of the family, it has four leucine-rich LD-motifs in the N-terminus and four LIM domains in the C-terminus. It may function in cell type-specific signaling by associating with interaction partners PYK2, FAK, PEP and p95PKL. When expressed in human leukocytic cells, leupaxin significantly suppressed integrin-mediated cell adhesion to fibronectin and the tyrosine phosphorylation of paxillin. These findings indicate that leupaxin may negatively regulate the functions of paxillin during integrin signaling. LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms.

The first LIM domain of lipoma preferred partner (LPP); The first LIM domain of lipoma preferred partner (LPP): LPP is a member of the zyxin LIM protein family and contains three LIM zinc-binding domains at the C-terminal and proline-rich region at the N-terminal. LPP initially identified as the most frequent translocation partner of HMGA2 (High Mobility Group A2) in a subgroup of benign tumors of adipose tissue (lipomas). It was also shown to be rearranged in a number of other soft tissues, as well as in a case of acute monoblastic leukemia. In addition to its involvement in tumors, LPP was inedited as a smooth muscle restricted LIM protein that plays an important role in SMC migration. LPP is localized at sites of cell adhesion, cell-cell contacts and transiently in the nucleus. In nucleus, it acts as a coactivator for the ETS domain transcription factor PEA3. In addition to PEA3, it interacts with alpha-actinin,vasodilator stimulated phosphoprotein (VASP),Palladin, and Scrib. The LIM domains are the main focal adhesion targeting elements and that the proline- rich region, which harbors binding sites for alpha-actinin and vasodilator- stimulated phosphoprotein (VASP), has a weak targeting capacity. As in other LIM domains, this domain family is 50-60 amino acids in size and shares two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein.

The third LIM domain of actin binding LIM (abLIM) proteins; The third LIM domain of actin binding LIM (abLIM) proteins: Three homologous members of the abLIM protein family have been identified; abLIM-1, abLIM-2 and abLIM-3. The N-terminal of abLIM consists of four tandem repeats of LIM domains and the C-terminal of acting binding LIM protein is a villin headpiece domain, which has strong actin binding activity. The abLIM-1, which is expressed in retina, brain, and muscle tissue, has been indicated to function as a tumor suppressor. AbLIM-2 and -3, mainly expressed in muscle and neuronal tissue, bind to F-actin strongly. They may serve as a scaffold for signaling modules of the actin cytoskeleton and thereby modulate transcription. It has shown that LIM domains of abLIMs interact with STARS (striated muscle activator of Rho signaling), which directly binds actin and stimulates serum-response factor (SRF)-dependent transcription. All LIM domains are 50-60 amino acids in size and share two characteristic highly conserved zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms.

The first LIM domain of Ajuba-like proteins; The first LIM domain of Ajuba-like proteins: Ajuba like LIM protein family includes three highly homologous proteins Ajuba, Limd1, and WTIP. Members of the family contain three tandem C-terminal LIM domains and a proline-rich N-terminal region. This family of proteins functions as scaffolds, participating in the assembly of numerous protein complexes. In the cytoplasm, Ajuba binds Grb2 to modulate serum-stimulated ERK activation. Ajuba also recruits the TNF receptor-associated factor 6 (TRAF6) to p62 and activates PKCKappa activity. Ajuba interacts with alpha-catenin and F-actin to contribute to the formation or stabilization of adheren junctions by linking adhesive receptors to the actin cytoskeleton. Although Ajuba is a cytoplasmic protein, it can shuttle into the nucleus. In nucleus, Ajuba functions as a corepressor for the zinc finger-protein Snail. It binds to the SNAG repression domain of Snail through its LIM region. Arginine methyltransferase-5 (Prmt5), a protein in the complex, is recruited to Snai l through an interaction with Ajuba. This ternary complex functions to repress E-cadherin, a Snail target gene. In addition, Ajuba contains functional nuclear-receptor interacting motifs and selectively interacts with retinoic acid receptors (RARs) and rexinoid receptor (RXRs) to negatively regulate retinoic acid signaling. Wtip, the Wt1-interacting protein, was originally identified as an interaction partner of the Wilms tumour protein 1 (WT1). Wtip is involved in kidney and neural crest development. Wtip interacts with the receptor tyrosine kinase Ror2 and inhibits canonical Wnt signaling. LIMD1 was reported to inhibit cell growth and metastases. The inhibition may be mediated through an interaction with the protein barrier-to-autointegration (BAF), a component of SWI/SNF chromatin-remodeling protein; or through the interaction with retinoblastoma protein (pRB), resulting in inhibition of E2F-mediated transcription, and expression of the majority of genes with E2F1- responsive elements. Recently, Limd1 was shown to interact with the p62/sequestosome protein and influence IL-1 and RANKL signaling by facilitating the assembly of a p62/TRAF6/a-PKC multi-protein complex. The Limd1-p62 interaction affects both NF-kappaB and AP-1 activity in epithelial cells and osteoclasts. Moreover, LIMD1 functions as tumor repressor to block lung tumor cell line in vitro and in vivo. Recent studies revealed that LIM proteins Wtip, LIMD1 and Ajuba interact with components of RNA induced silencing complexes (RISC) as well as eIF4E and the mRNA m7GTP cap-protein complex and are required for microRNA-mediated gene silencing. As in other LIM domains, this domain family is 50-60 amino acids in size and shares two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein.

The second LIM domain of Zyxin; The second LIM domain of Zyxin: Zyxin exhibits three copies of the LIM domain, an extensive proline-rich domain and a nuclear export signal. Localized at sites of cellsubstratum adhesion in fibroblasts, Zyxin interacts with alpha-actinin, members of the cysteine-rich protein (CRP) family, proteins that display Src homology 3 (SH3) domains and Ena/VASP family members. Zyxin and its partners have been implicated in the spatial control of actin filament assembly as well as in pathways important for cell differentiation. In addition to its functions at focal adhesion plaques, recent work has shown that zyxin moves from the sites of cell contacts to the nucleus, where it directly participates in the regulation of gene expression. As in other LIM domains, this domain family is 50-60 amino acids in size and shares two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms.

The second LIM domain of Four and a half LIM domains protein (FHL); The second LIM domain of Four and a half LIM domains protein (FHL): LIM-only protein family consists of five members, designated FHL1, FHL2, FHL3, FHL5 and LIMPETin. The first four members are composed of four complete LIM domains arranged in tandem and an N-terminal single zinc finger domain with a consensus sequence equivalent to the C-terminal half of a LIM domain. LIMPETin is an exception, containing six LIM domains. FHL1, 2 and 3 are predominantly expressed in muscle tissues, and FHL5 is highly expressed in male germ cells. FHL proteins exert their roles as transcription co-activators or co-repressors through a wide array of interaction partners. For example, FHL1 binds to Myosin-binding protein C, regulating myosin filament formation and sarcomere assembly. FHL2 has shown to interact with more than 50 different proteins, including receptors, structural proteins, transcription factors and cofactors, signal transducers, splicing factors, DNA replication and repair enzymes, and metabolic enzymes. FHL3 int eracts with many transcription factors, such as CREB, BKLF/KLF3, CtBP2, MyoD, and MZF_1. FHL5 is a tissue-specific coactivator of CREB/CREM family transcription factors. LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs.

The first LIM domain of ZASP/Cypher family; The first LIM domain of ZASP/Cypher family: ZASP was identified in human heart and skeletal muscle and Cypher is a mice ortholog of ZASP. ZASP/Cyppher contains three LIM domains at the C-terminus and a PDZ domain at N-terminus. ZASP/Cypher is required for maintenance of Z-line structure during muscle contraction, but not required for Z-line assembly. In heart, Cypher/ZASP plays a structural role through its interaction with cytoskeletal Z-line proteins. In addition, there is increasing evidence that Cypher/ZASP also performs signaling functions. Studies reveal that Cypher/ZASP interacts with and directs PKC to the Z-line, where PKC phosphorylates downstream signaling targets. LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs.

The first LIM domain of Thyroid receptor-interacting protein 6 (TRIP6); The first LIM domain of Thyroid receptor-interacting protein 6 (TRIP6): TRIP6 is a member of the zyxin LIM protein family and contains three LIM zinc-binding domains at the C-terminal. TRIP6 protein localizes to focal adhesion sites and along actin stress fibers. Recruitment of this protein to the plasma membrane occurs in a lysophosphatidic acid (LPA)-dependent manner. TRIP6 recruits a number of molecules involved in actin assembly, cell motility, survival and transcriptional control. The function of TRIP6 in cell motility is regulated by Src-dependent phosphorylation at a Tyr residue. The phosphorylation activates the coupling to the Crk SH2 domain, which is required for the function of TRIP6 in promoting lysophosphatidic acid (LPA)-induced cell migration. TRIP6 can shuttle to the nucleus to serve as a coactivator of AP-1 and NF-kappaB transcriptional factors. Moreover, TRIP6 can form a ternary complex with the NHERF2 PDZ protein and LPA2 receptor to regulate LPA-induced activation of ERK and AKT, rendering cells resistant to chemotherapy. Recent evidence shows that TRIP6 antagonizes Fas-Induced apoptosis by enhancing the antiapoptotic effect of LPA in cells. As in other LIM domains, this domain family is 50-60 amino acids in size and shares two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms.

The second LIM domain of Lhx2 and Lhx9 family; The second LIM domain of Lhx2 and Lhx9 family: Lhx2 and Lhx9 are highly homologous LHX regulatory proteins. They belong to the LHX protein family, which features two tandem N-terminal LIM domains and a C-terminal DNA binding homeodomain. Members of LHX family are found in the nucleus and act as transcription factors or cofactors. LHX proteins are critical for the development of specialized cells in multiple tissue types, including the nervous system, skeletal muscle, the heart, the kidneys, and endocrine organs, such as the pituitary gland and the pancreas. Although Lhx2 and Lhx9 are highly homologous, they seems to play regulatory roles in different organs. In animals, Lhx2 plays important roles in eye, cerebral cortex, limb, the olfactory organs, and erythrocyte development. Lhx2 gene knockout mice exhibit impaired patterning of the cortical hem and the telencephalon of the developing brain, and a lack of development in olfactory structures. Lhx9 is expressed in several regions of the developing mouse brain, the spinal cord, the pancreas, in limb mesenchyme, and in the urogenital region. Lhx9 plays critical roles in gonad development. Homozygous mice lacking functional Lhx9 alleles exhibit numerous urogenital defects, such as gonadal agenesis, infertility, and undetectable levels of testosterone and estradiol coupled with high FSH levels. Lhx9 null mice are phenotypically female, even those that are genotypically male. As in other LIM domains, this domain family is 50-60 amino acids in size and shares two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms.

The first LIM domain of LIMK1 (LIM domain Kinase 1); The first LIM domain of LIMK1 (LIM domain Kinase 1): LIMK1 belongs to the LIMK protein family, which comprises LIMK1 and LIMK2. LIMK contains two LIM domains, a PDZ domain, and a kinase domain. LIMK is involved in the regulation of actin polymerization and microtubule disassembly. LIMK influences architecture of the actin cytoskeleton by regulating the activity of the cofilin family proteins cofilin1, cofilin2, and destrin. The mechanism of the activation is to phosphorylates cofilin on serine 3 and inactivates its actin-severing activity, and altering the rate of actin depolymerization. LIMKs can function in both cytoplasm and nucleus. Both LIMK1 and LIMK2 can act in the nucleus to suppress Rac/Cdc42-dependent cyclin D1 expression. LIMK1 is expressed in all tissues and is localized to focal adhesions in the cell. LIMK1 can form homodimers upon binding of HSP90 and is activated by Rho effector Rho kinase and MAPKAPK2. LIMK1 is important for normal central nervous system development, and its deletion has been implicated in the development of the human genetic disorder Williams syndrome. Moreover, LIMK1 up-regulates the promoter activity of urokinase type plasminogen activator and induces its mRNA and protein expression in breast cancer cells. The LIM domains have been shown to play an important role in regulating kinase activity and likely also contribute to LIMK function by acting as sites of protein-to-protein interactions. All LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein complexes.

The second LIM domain of paxillin; The second LIM domain of paxillin: Paxillin is an adaptor protein, which recruits key components of the signal-transduction machinery to specific sub-cellular locations to respond to environmental changes rapidly. The C-terminal region of paxillin contains four LIM domains which target paxillin to focal adhesions, presumably through a direct association with the cytoplasmic tail of beta-integrin. The N-terminal of paxillin is leucine-rich LD-motifs. Paxillin is found at the interface between the plasma membrane and the actin cytoskeleton. The binding partners of paxillin are diverse and include protein tyrosine kinases, such as Src and FAK, structural proteins, such as vinculin and actopaxin, and regulators of actin organization. Paxillin recruits these proteins to their function sites to control the dynamic changes in cell adhesion, cytoskeletal reorganization and gene expression. LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein complexes.

The second LIM domain of protein PINCH; The second LIM domain of protein PINCH: PINCH plays a pivotal role in the assembly of focal adhesions (FAs), regulating diverse functions in cell adhesion, growth, and differentiation through LIM-mediated protein-protein interactions. PINCH comprises an array of five LIM domains that interact with integrin-linked kinase (ILK), Nck2 (also called Nckbeta or Grb4) and other interaction partners. These interactions are essential for triggering the FA assembly and for relaying diverse mechanical and biochemical signals between Cell-extracellular matrix and the actin cytoskeleton. LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein complexes.

The second LIM domain of Leupaxin; The second LIM domain of Leupaxin: Leupaxin is a cytoskeleton adaptor protein, which is preferentially expressed in hematopoietic cells. Leupaxin belongs to the paxillin focal adhesion protein family. Same as other members of the family, it has four leucine-rich LD-motifs in the N-terminus and four LIM domains in the C-terminus. It may function in cell type-specific signaling by associating with interaction partners PYK2, FAK, PEP and p95PKL. When expressed in human leukocytic cells, leupaxin significantly suppressed integrin-mediated cell adhesion to fibronectin and the tyrosine phosphorylation of paxillin. These findings indicate that leupaxin may negatively regulate the functions of paxillin during integrin signaling. LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein complexes.

The LIM domains of thymus LIM protein (TLP); The LIM domain of thymus LIM protein (TLP) like proteins: This family includes the LIM domains of TLP and CRIP (Cysteine-Rich Intestinal Protein). TLP is the distant member of the CRP family of proteins. TLP has two isomers (TLP-A and TLP-B) and sharing approximately 30% with each of the three other CRPs. Like CRP1, CRP2 and CRP3/MLP, TLP has two LIM domains, connected by a flexible linker region. Unlike the CRPs, TLP lacks the nuclear targeting signal (K/R-K/R-Y-G-P-K) and is localized solely in the cytoplasm. TLP is specifically expressed in the thymus in a subset of cortical epithelial cells. TLP has a role in development of normal thymus and in controlling the development and differentiation of thymic epithelial cells. CRIP is a short LIM protein with only one LIM domain. CRIP gene is developmentally regulated and can be induced by glucocorticoid hormones during the first three postnatal weeks. The domain shows close sequence homology to LIM domain of thymus LIM protein. However, unlike the TLP proteins which have two LIM domains, the members of this family have only one LIM domain. LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein complexes.

The second LIM domain of LIMK2 (LIM domain Kinase 2); The second LIM domain of LIMK2 (LIM domain Kinase 2): LIMK2 is a member of the LIMK protein family, which comprises LIMK1 and LIMK2. LIMK contains two LIM domains, a PDZ domain, and a kinase domain. LIMK is involved in the regulation of actin polymerization and microtubule disassembly. LIMK influences architecture of the actin cytoskeleton by regulating the activity of the cofilin family proteins cofilin1, cofilin2, and destrin. The mechanism of the activation is to phosphorylates cofilin on serine 3 and inactivates its actin-severing activity, altering the rate of actin depolymerisation. LIMK activity is activated by phosphorylation of a threonine residue within the activation loop of the kinase by p21-activated kinases 1 and 4 and by Rho kinase. LIMKs can function in both cytoplasm and nucleus. Both LIMK1 and LIMK2 can act in the nucleus to suppress Rac/Cdc42-dependent cyclin D1 expression. LIMK2 is expressed in all tissues. While LIMK1 localizes mainly at focal adhesions, LIMK2 is found in cytoplasmic punctae, suggesting that they may have different cellular functions. The activity of LIM kinase 2 to regulate cofilin phosphorylation is inhibited by the direct binding of Par-3. LIMK2 activation promotes cell cycle progression. The phenotype of Limk2 knockout mice shows a defect in spermatogenesis. The LIM domains have been shown to play an important role in regulating kinase activity and likely also contribute to LIMK function by acting as sites of protein-to-protein interactions. All LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein complexes.

The first LIM domain of lipoma preferred partner (LPP); The first LIM domain of lipoma preferred partner (LPP): LPP is a member of the zyxin LIM protein family and contains three LIM zinc-binding domains at the C-terminal and proline-rich region at the N-terminal. LPP initially identified as the most frequent translocation partner of HMGA2 (High Mobility Group A2) in a subgroup of benign tumors of adipose tissue (lipomas). It was also shown to be rearranged in a number of other soft tissues, as well as in a case of acute monoblastic leukemia. In addition to its involvement in tumors, LPP was inedited as a smooth muscle restricted LIM protein that plays an important role in SMC migration. LPP is localized at sites of cell adhesion, cell-cell contacts and transiently in the nucleus. In nucleus, it acts as a coactivator for the ETS domain transcription factor PEA3. In addition to PEA3, it interacts with alpha-actinin,vasodilator stimulated phosphoprotein (VASP),Palladin, and Scrib. The LIM domains are the main focal adhesion targeting elements and that the proline- rich region, which harbors binding sites for alpha-actinin and vasodilator- stimulated phosphoprotein (VASP), has a weak targeting capacity. As in other LIM domains, this domain family is 50-60 amino acids in size and shares two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein.
