TPR/MLP1/MLP2-like protein; The sequences featured in this family are similar to a region of human TPR protein and to yeast myosin-like proteins 1 (MLP1) and 2 (MLP2). These proteins share a number of features; for example, they all have coiled-coil regions and all three are associated with nuclear pores. TPR is thought to be a component of nuclear pore complex- attached intra-nuclear filaments, and is implicated in nuclear protein import. Moreover, its N-terminal region is involved in the activation of oncogenic kinases, possibly by mediating the dimerization of kinase domains or by targeting these kinases to the nuclear pore complex. MLP1 and MLP2 are involved in the process of telomere length regulation, where they are thought to interact with proteins such as Tel1p and modulate their activity.

calponin homology (CH) domain superfamily; CH domains are actin filament (F-actin) binding motifs, which may be present as a single copy or in tandem repeats (which increase binding affinity). They either function as autonomous actin binding motifs or serve a regulatory function. CH domains are found in cytoskeletal and signal transduction proteins, including actin-binding proteins like spectrin, alpha-actinin, dystrophin, utrophin, and fimbrin, as well as proteins essential for regulation of cell shape (cortexillins), and signaling proteins (Vav).

first calponin homology (CH) domain found in the beta spectrin family; The beta spectrin family includes beta-I, -II, -III, -IV and -V 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-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. Beta-III spectrin is also called spectrin beta chain, non-erythrocytic 2 (SPTBN2), or spinocerebellar ataxia 5 protein (SCA5). Beta-V spectrin, also called spectrin beta chain, non-erythrocytic 5 (SPTBN5), is a mammalian ortholog of Drosophila beta H spectrin. Beta-III and Beta-V spectrins may play crucial roles as longer actin-membrane cross-linkers or fulfill the need for greater extensible flexibility than can be provided by the other smaller conventional spectrins. 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. CH domains are actin filament (F-actin) binding motifs.

first calponin homology (CH) domain found in the synaptic nuclear envelope protein family; The synaptic nuclear envelope (SYNE) family includes SYNE-1, -2 and calmin. SYNE-1 (also called nesprin-1, enaptin, KASH domain-containing protein 1, KASH1, myocyte nuclear envelope protein 1, MYNE-1, or nuclear envelope spectrin repeat protein 1) and SYNE-2 (also called nesprin-2, KASH domain-containing protein 2, KASH2, nuclear envelope spectrin repeat protein 2, nucleus and actin connecting element protein, or protein NUANCE) may act redundantly. They are multi-isomeric modular proteins which form a linking network between organelles and the actin cytoskeleton to maintain subcellular spatial organization. They also act as components of the LINC (LInker of Nucleoskeleton and Cytoskeleton) complex, which is involved in the connection between the nuclear lamina and the cytoskeleton. Calmin, also called calponin-like transmembrane domain protein, is a protein with calponin homology (CH) and transmembrane domains expressed in maturing spermatogenic cells. It may be involved in the development and/or maintenance of neuronal functions. 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 filamin family; The filamin family includes filamin-A (FLN-A), filamin-B (FLN-B) and filamin-C (FLN-C). Filamins function to anchor various transmembrane proteins to the actin cytoskeleton. FLN-A is also called actin-binding protein 280 (ABP-280), alpha-filamin, endothelial actin-binding protein, filamin-1, or non-muscle filamin. 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 first CH domain. CH domains are actin filament (F-actin) binding motifs.

second 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 second CH domain. CH domains are actin filament (F-actin) binding motifs.

first calponin homology (CH) domain found in dystonin and similar proteins; 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. Dystonin contains two copies of the CH domain. This model corresponds to the first CH domain. CH domains are actin filament (F-actin) binding motifs.

Herpes virus major outer envelope glycoprotein (BLLF1); This family consists of the BLLF1 viral late glycoprotein, also termed gp350/220. It is the most abundantly expressed glycoprotein in the viral envelope of the Herpesviruses and is the major antigen responsible for stimulating the production of neutralising antibodies in vivo.
