first calponin homology (CH) domain found in the plectin/dystonin/MACF1 family; This family includes plectin, dystonin and microtubule-actin cross-linking factor 1, isoforms 1/2/3/5 (MACF1). Plectin, also called PCN, PLTN, hemidesmosomal protein 1 (HD1), or plectin-1, is a structural component of muscle. It interlinks intermediate filaments with microtubules and microfilaments, and anchors intermediate filaments to desmosomes or hemidesmosomes. It could also bind muscle proteins such as actin to membrane complexes in muscle. Dystonin, also called 230 kDa bullous pemphigoid antigen, 230/240 kDa bullous pemphigoid antigen, bullous pemphigoid antigen 1 (BPA or BPAG1), dystonia musculorum protein, or hemidesmosomal plaque protein, is a cytoskeletal linker protein that acts as an integrator of intermediate filaments, actin, and microtubule cytoskeleton networks. It is required for anchoring either intermediate filaments to the actin cytoskeleton in neural and muscle cells, or keratin-containing intermediate filaments to hemidesmosomes in epithelial cells. MACF1, also called 620 kDa actin-binding protein (ABP620), actin cross-linking family protein 7 (ACF7), macrophin-1, or trabeculin-alpha, is a large protein containing numerous spectrin and leucine-rich repeat (LRR) domains. It facilitates actin-microtubule interactions at the cell periphery and couples the microtubule network to cellular junctions. Members of this family contain two copies of the CH domain. This model corresponds to the first CH domain. CH domains are actin filament (F-actin) binding motifs.

chromosome segregation protein SMC, common bacterial type; SMC (structural maintenance of chromosomes) proteins bind DNA and act in organizing and segregating chromosomes for partition. SMC proteins are found in bacteria, archaea, and eukaryotes. This family represents the SMC protein of most bacteria. The smc gene is often associated with scpB (TIGR00281) and scpA genes, where scp stands for segregation and condensation protein. SMC was shown (in Caulobacter crescentus) to be induced early in S phase but present and bound to DNA throughout the cell cycle.

Src Homology 3 domain of Tec-like Protein Tyrosine Kinases; The Tec (Tyrosine kinase expressed in hepatocellular carcinoma) subfamily is composed of Tec, Btk, Bmx (Etk), Itk (Tsk, Emt), Rlk (Txk), and similar proteins. They are cytoplasmic (or nonreceptor) tyr kinases containing Src homology protein interaction domains (SH3, SH2) N-terminal to the catalytic tyr kinase domain. Most Tec subfamily members (except Rlk) also contain an N-terminal pleckstrin homology (PH) domain, which binds the products of PI3K and allows membrane recruitment and activation. In addition, some members contain the Tec homology (TH) domain, which contains proline-rich and zinc-binding regions. Tec kinases are expressed mainly by haematopoietic cells, although Tec and Bmx are also found in endothelial cells. B-cells express Btk and Tec, while T-cells express Itk, Txk, and Tec. Collectively, Tec kinases are expressed in a variety of myeloid cells such as mast cells, platelets, macrophages, and dendritic cells. Each Tec kinase shows a distinct cell-type pattern of expression. The function of Tec kinases in lymphoid cells have been studied extensively. They play important roles in the development, differentiation, maturation, regulation, survival, and function of B-cells and T-cells. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

first calponin homology (CH) domain found in the plectin/dystonin/MACF1 family; This family includes plectin, dystonin and microtubule-actin cross-linking factor 1, isoforms 1/2/3/5 (MACF1). Plectin, also called PCN, PLTN, hemidesmosomal protein 1 (HD1), or plectin-1, is a structural component of muscle. It interlinks intermediate filaments with microtubules and microfilaments, and anchors intermediate filaments to desmosomes or hemidesmosomes. It could also bind muscle proteins such as actin to membrane complexes in muscle. Dystonin, also called 230 kDa bullous pemphigoid antigen, 230/240 kDa bullous pemphigoid antigen, bullous pemphigoid antigen 1 (BPA or BPAG1), dystonia musculorum protein, or hemidesmosomal plaque protein, is a cytoskeletal linker protein that acts as an integrator of intermediate filaments, actin, and microtubule cytoskeleton networks. It is required for anchoring either intermediate filaments to the actin cytoskeleton in neural and muscle cells, or keratin-containing intermediate filaments to hemidesmosomes in epithelial cells. MACF1, also called 620 kDa actin-binding protein (ABP620), actin cross-linking family protein 7 (ACF7), macrophin-1, or trabeculin-alpha, is a large protein containing numerous spectrin and leucine-rich repeat (LRR) domains. It facilitates actin-microtubule interactions at the cell periphery and couples the microtubule network to cellular junctions. Members of this family contain two copies of the CH domain. This model corresponds to the first CH domain. CH domains are actin filament (F-actin) binding motifs.

first calponin homology (CH) domain found in the beta-I spectrin-like subfamily; The beta-I spectrin-like family includes beta-I, -II, -III and -IV spectrins. Spectrin is an actin crosslinking and molecular scaffold protein that links the plasma membrane to the actin cytoskeleton, and functions in the determination of cell shape, arrangement of transmembrane proteins, and organization of organelles. It is composed of two antiparallel dimers of alpha- and beta- subunits. Beta-I spectrin, also called spectrin beta chain, erythrocytic (SPTB), may be involved in anaemia pathogenesis. Beta-II spectrin, also called spectrin beta chain, non-erythrocytic 1 (SPTBN1), or fodrin beta chain, is a component of fodrin, which is the general spectrin-like protein that seems to be involved in secretion. Fodrin interacts with calmodulin in a calcium-dependent manner and is thus a candidate for the calcium-dependent movement of the cytoskeleton at the membrane. Beta-III spectrin, also called spectrin beta chain, non-erythrocytic 2 (SPTBN2), or spinocerebellar ataxia 5 protein (SCA5), may play a crucial role as a longer actin-membrane cross-linker or fulfill the need for greater extensible flexibility than can be provided by the other smaller conventional spectrins. Beta-IV spectrin is also called spectrin, non-erythroid beta chain 3 (SPTBN3) or spectrin beta chain, non-erythrocytic 4 (SPTBN4). Its mutation associates with congenital myopathy, neuropathy, and central deafness. Members of this subfamily contain two copies of the CH domain. This model corresponds to the first CH domain.

first calponin homology (CH) domain found in the dystrophin family; The dystrophin family includes dystrophin and its paralog, utrophin. Dystrophin, encoded by the DMD gene, is a large, submembrane cytoskeletal protein that is the main component of the dystrophin-glycoprotein complex (DGC) in skeletal muscles. It links the transmembrane DGC to the actin cytoskeleton through binding strongly to the cytoplasmic tail of beta-dystroglycan, the transmembrane subunit of a highly O-glycosylated cell-surface protein. Dystrophin is also involved in maintaining the structural integrity of cells, as well as in the formation of the blood-brain barrier (BBB). Utrophin, also called dystrophin-related protein 1 (DRP-1), is an autosomal dystrophin homolog that increases dystrophic muscle function and reduces pathology. It is broadly expressed in both the mRNA and protein levels, and occurs in the cerebrovascular endothelium. Utrophin forms the utrophin-glycoprotein complex (UGC) by interacting with dystroglycans (DGs) and sarcoglycan-dystroglycans, as well as sarcoglycan and sarcospan (SG-SSPN) subcomplexes. It may act as a scaffolding protein that stabilizes lipid microdomains and clusters mechanosensitive channel subunits, and links the F-actin cytoskeleton to the cell membrane via the associated glycoprotein complex. Members of this family contain two copies of the CH domain. This model corresponds to the first CH domain. CH domains are actin filament (F-actin) binding motifs.

It links the transmembrane DGC to the actin cytoskeleton through binding strongly to the cytoplasmic tail of beta-dystroglycan, the transmembrane subunit of a highly O-glycosylated cell-surface protein. It is involved in maintaining the structural integrity of cells, as well as in the formation of the blood-brain barrier (BBB). Mutations in dystrophin lead to Duchenne muscular dystrophy (DMD). Moreover, dystrophin deficiency is associated with abnormal cerebral diffusion and perfusion, as well as in acute Trypanosoma cruzi infection. The dystrophin subfamily has been characterized by a compact cluster of domains comprising four EF-hand-like motifs and a ZZ-domain, followed by a looser region with two coiled-coils.

MICAL-L2, also called junctional Rab13-binding protein (JRAB), or molecule interacting with CasL-like 2, acts as an effector of small Rab GTPases which is involved in junctional complexes assembly through the regulation of cell adhesion molecule transport to the plasma membrane, and actin cytoskeleton reorganization. It regulates the endocytic recycling of occludins, claudins, and E-cadherin to the plasma membrane and may thereby regulate the establishment of tight junctions and adherens junctions.

calponin homology (CH) domain found in molecule interacting with CasL protein 2 (MICAL-2), MICAL-3, and similar proteins; Molecule interacting with CasL protein (MICAL) is a large, multidomain, cytosolic protein with a single LIM domain, a calponin homology (CH) domain and a flavoprotein monooxygenase (MO) domain. In Drosophila, MICAL is expressed in axons, interacts with the neuronal A (PlexA) receptor and is required for Semaphorin 1a (Sema-1a)-PlexA-mediated repulsive axon guidance. The LIM and CH domains mediate interactions with the cytoskeleton, cytoskeletal adaptor proteins, and other signaling proteins. The flavoprotein MO is required for semaphorin-plexin repulsive axon guidance during axonal pathfinding in the Drosophila neuromuscular system. In addition, MICAL functions to interact with Rab13 and Rab8 to coordinate the assembly of tight junctions and adherens junctions in epithelial cells. Thus, MICAL is also called junctional Rab13-binding protein (JRAB). Members of this family, which includes MICAL-2, MICAL-3, and similar proteins, contain one CH domain.

Spectrin repeat; Spectrin repeat-domains are found in several proteins involved in cytoskeletal structure. These include spectrin, alpha-actinin and dystrophin. The sequence repeat used in this family is taken from the structural repeat in reference. The spectrin domain- repeat forms a three helix bundle. The second helix is interrupted by proline in some sequences. The repeats are defined by a characteriztic tryptophan (W) residue at position 17 in helix A and a leucine (L) at 2 residues from the carboxyl end of helix C. Although the domain occurs in multiple repeats along sequences, the domains are actually stable on their own - ie they act, biophysically, like domains rather than repeats that along function when aggregated.

third calponin homology (CH) domain found in the Arabidopsis thaliana fimbrin family; The Arabidopsis thaliana fimbrin (AtFIM) family includes Fimbrin-1, -2, -3, -4, and -5, which cross-link actin filaments (F-actin) in a calcium independent manner. They stabilize and prevent F-actin depolymerization mediated by profilin. They act as key regulators of actin cytoarchitecture, probably involved in cell cycle, cell division, cell elongation and cytoplasmic tractus. AtFIM5 is an actin bundling factor that is required for pollen germination and pollen tube growth. Members of this family contain four copies of the CH domain. This model corresponds to the third CH domain. CH domains are actin filament (F-actin) binding motifs.

The sequence repeat used in this family is taken from the structural repeat in reference. The spectrin domain- repeat forms a three helix bundle. The second helix is interrupted by proline in some sequences. The repeats are defined by a characteriztic tryptophan (W) residue at position 17 in helix A and a leucine (L) at 2 residues from the carboxyl end of helix C. Although the domain occurs in multiple repeats along sequences, the domains are actually stable on their own - ie they act, biophysically, like domains rather than repeats that along function when aggregated.

family of the cytolysin A (ClyA) family alpha pore-forming toxins (alpha-PFT) including Bacillus cereus HblB, Aeromonas hydrophila AhlB, Bacillus thuringiensis Cry6Aa and similar proteins; This family belongs to the ClyA family of alpha-PFT bacterial toxins. PFTs form the major group of virulence factors in many pathogenic bacteria and in general are critical components of the molecular offensive and defensive machinery of cells in all kingdoms of life. Bacterial PFTs facilitate the takeover of host resources by puncturing holes in the membrane. PFTs can be classified as alpha-PFTs and beta-PFTs depending on the secondary structures of their membrane component. Alpha-PFTs use a ring of amphipathic helices while beta-PFTs use a beta-barrel to construct the pore. Members of this family include the toxins: Bacillus cereus hemolysin binding component B (HblB or HBL-B) of the diarrheal enterotoxin hemolysin BL, Aeromonas hydrophila hemolytic (Ahl) component B (AhlB) of the tripartite AhlABC toxin, Vibrio cholerae cytotoxin motility associated killing factor A (MakA) cytotoxin, Xenorhabdus nematophila alpha-xenorhabdolysin (XaxA), Bacillus thuringiensis crystal 6Aa (Cry6Aa) parasporal crystal (Cry) toxin, and Bacillus cereus non-hemolytic enterotoxin (Nhe) component A (NheA) of the non-hemolytic enterotoxin Nhe, which, despite its name, is hemolytic, among others. In solution, ClyA proteins have an elongated, almost entirely alpha-helical structure, except for a short hydrophobic beta-hairpin known as the beta-tongue. Pore formation by ClyA requires circular oligomerization of the toxin by a sequential mechanism. This, in turn, concentrates the amphipathic helices in the center of the ring-like structure, forming a helical barrel that inserts into the membrane by a wedge-like mechanism. Compared with ClyA, NheA is almost entirely alpha-helical with an enlarged "head" domain, and an enlarged beta-tongue; it has been proposed that NheA could even form beta-barrel pores. Alpha-PFTs with similar structures are increasingly being found in eukaryotes, in particular as components of the immune systems of animals. This family may be distantly related to Escherichia coli alpha-PFT hemolysin E (HlyE, also known as ClyA or SheA).

Src Homology 3 domain of Tec-like Protein Tyrosine Kinases; The Tec (Tyrosine kinase expressed in hepatocellular carcinoma) subfamily is composed of Tec, Btk, Bmx (Etk), Itk (Tsk, Emt), Rlk (Txk), and similar proteins. They are cytoplasmic (or nonreceptor) tyr kinases containing Src homology protein interaction domains (SH3, SH2) N-terminal to the catalytic tyr kinase domain. Most Tec subfamily members (except Rlk) also contain an N-terminal pleckstrin homology (PH) domain, which binds the products of PI3K and allows membrane recruitment and activation. In addition, some members contain the Tec homology (TH) domain, which contains proline-rich and zinc-binding regions. Tec kinases are expressed mainly by haematopoietic cells, although Tec and Bmx are also found in endothelial cells. B-cells express Btk and Tec, while T-cells express Itk, Txk, and Tec. Collectively, Tec kinases are expressed in a variety of myeloid cells such as mast cells, platelets, macrophages, and dendritic cells. Each Tec kinase shows a distinct cell-type pattern of expression. The function of Tec kinases in lymphoid cells have been studied extensively. They play important roles in the development, differentiation, maturation, regulation, survival, and function of B-cells and T-cells. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

It promotes orthogonal branching of actin filaments and links actin filaments to membrane glycoproteins. It also serves as a scaffold for a wide range of cytoplasmic signaling proteins. FLN-B is also called ABP-278, ABP-280 homolog, actin-binding-like protein, beta-filamin, filamin homolog 1 (Fh1), filamin-3, thyroid autoantigen, truncated actin-binding protein, or truncated ABP. It connects cell membrane constituents to the actin cytoskeleton and may also promote orthogonal branching of actin filaments as well as link actin filaments to membrane glycoproteins. FLN-C, also called FLNc, ABP-280-like protein, ABP-L, actin-binding-like protein, filamin-2, or gamma-filamin, is a muscle-specific filamin that plays a central role in muscle cells, probably by functioning as a large actin-cross-linking protein. It may be involved in reorganizing the actin cytoskeleton in response to signaling events, and may also display structural functions at the Z lines in muscle cells. FLN-C is critical for normal myogenesis and for maintaining the structural integrity of the muscle fibers. This family also includes Drosophila melanogaster protein jitterbug (Jbug), which is an actin-meshwork organizing protein containing three copies of the CH domain. Other members of this family contain two copies of the CH domain. This model corresponds to the second CH domain. CH domains are actin filament (F-actin) binding motifs.

second calponin homology (CH) domain found in the family of plastin; The plastin family includes plastin-1, -2, and -3. Plastin-1, also called intestine-specific plastin, or I-plastin, is an actin-bundling protein in the absence of calcium. Plastin-2, also called L-plastin, or LC64P, or lymphocyte cytosolic protein 1 (LCP-1), is an actin-binding protein that plays a role in the activation of T-cells in response to costimulation through TCR/CD3 and CD2 or CD28. It modulates the cell surface expression of IL2RA/CD25 and CD69. Plastin-3, also called T-plastin, is an actin-bundling protein found in intestinal microvilli, hair cell stereocilia, and fibroblast filopodia. It may play a role in the regulation of bone development. Members of this family contain four copies of the CH domain. This model corresponds to the second CH domain. CH domains are actin filament (F-actin) binding motifs.

chromosome segregation protein SMC, common bacterial type; SMC (structural maintenance of chromosomes) proteins bind DNA and act in organizing and segregating chromosomes for partition. SMC proteins are found in bacteria, archaea, and eukaryotes. This family represents the SMC protein of most bacteria. The smc gene is often associated with scpB (TIGR00281) and scpA genes, where scp stands for segregation and condensation protein. SMC was shown (in Caulobacter crescentus) to be induced early in S phase but present and bound to DNA throughout the cell cycle.

chromosome segregation protein SMC, primarily archaeal type; SMC (structural maintenance of chromosomes) proteins bind DNA and act in organizing and segregating chromosomes for partition. SMC proteins are found in bacteria, archaea, and eukaryotes. It is found in a single copy and is homodimeric in prokaryotes, but six paralogs (excluded from this family) are found in eukarotes, where SMC proteins are heterodimeric. This family represents the SMC protein of archaea and a few bacteria (Aquifex, Synechocystis, etc); the SMC of other bacteria is described by TIGR02168. The N- and C-terminal domains of this protein are well conserved, but the central hinge region is skewed in composition and highly divergent.

Spectrin repeat; Spectrin repeat-domains are found in several proteins involved in cytoskeletal structure. These include spectrin, alpha-actinin and dystrophin. The sequence repeat used in this family is taken from the structural repeat in reference. The spectrin domain- repeat forms a three helix bundle. The second helix is interrupted by proline in some sequences. The repeats are defined by a characteriztic tryptophan (W) residue at position 17 in helix A and a leucine (L) at 2 residues from the carboxyl end of helix C. Although the domain occurs in multiple repeats along sequences, the domains are actually stable on their own - ie they act, biophysically, like domains rather than repeats that along function when aggregated.

second calponin homology (CH) domain found in the plastin/fimbrin family; This family includes plastin and fimbrin. Plastin has three isoforms, plastin-1, -2, and -3, which are all actin-bundling proteins. Plastin-1, also called intestine-specific plastin, or I-plastin, is an actin-bundling protein in the absence of calcium. Plastin-2, also called L-plastin, LC64P, or lymphocyte cytosolic protein 1 (LCP-1), plays a role in the activation of T-cells in response to costimulation through TCR/CD3 and CD2 or CD28. It modulates the cell surface expression of IL2RA/CD25 and CD69. Plastin-3, also called T-plastin, is found in intestinal microvilli, hair cell stereocilia, and fibroblast filopodia. It may play a role in the regulation of bone development. Fimbrin has been found in plants and fungi. Arabidopsis thaliana fimbrin (AtFIM) includes fimbrin-1, -2, -3, -4, and -5; they cross-link actin filaments (F-actin) in a calcium independent manner. They stabilize and prevent F-actin depolymerization mediated by profilin. They act as key regulators of actin cytoarchitecture, probably involved in cell cycle, cell division, cell elongation and cytoplasmic tractus. AtFIM5 is an actin bundling factor that is required for pollen germination and pollen tube growth. Fungal fimbrin binds to actin, and functionally associates with actin structures involved in the development and maintenance of cell polarity. Members of this family contain four copies of the CH domain. This model corresponds to the second CH domain. CH domains are actin filament (F-actin) binding motifs.

first calponin homology (CH) domain found in the parvin family; The parvin family includes alpha-parvin, beta-parvin, and gamma-parvin. Alpha-parvin, also called actopaxin, calponin-like integrin-linked kinase-binding protein (CH-ILKBP), or matrix-remodeling-associated protein 2, plays a role in sarcomere organization and in smooth muscle cell contraction. It is required for normal development of the embryonic cardiovascular system, and for normal septation of the heart outflow tract. Beta-parvin, also called affixin, is an adapter protein that plays a role in integrin signaling via ILK and in activation of the GTPases Cdc42 and Rac1 by guanine exchange factors, such as ARHGEF6. Both alpha-parvin and beta-parvin are involved in the reorganization of the actin cytoskeleton and the formation of lamellipodia, and both play roles in cell adhesion, cell spreading, establishment or maintenance of cell polarity, and cell migration. Gamma-parvin probably plays a role in the regulation of cell adhesion and cytoskeleton organization. Members of this family contain two copies of the CH domain. This model corresponds to the first CH domain. CH domains are actin filament (F-actin) binding motifs.
