Known members of the Mical-like family includes single LIM domain containing proteins, Mical (molecule interacting with CasL), pollen specific protein SF3, Eplin, xin actin-binding repeat-containing protein 2 (XIRP2), and Ltd-1. The members of this family function mainly at the cytoskeleton and focal adhesions. They interact with transcription factors or other signaling molecules to play roles in muscle development, neuronal differentiation, cell growth, and mobility. 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.

Bivalent Mical/EHBP Rab binding domain; A variety of different effector proteins interact specifically with GTP-bound Rab proteins and mediate their versatile roles in membrane trafficking, including budding of vesicles from a donor membrane, directed transport through the cell and finally tethering and fusion with a target membrane. The 'bivalent Mical/EHBP Rab binding' (bMERB) domain is a Rab effector domain that is present in proteins of the Mical and EHBP families, both known to act in endosomal trafficking. The bMERB domain displays a preference for Rab8 family proteins (Rab8, 10, 13 and 15) and at least some of the bMERB domains contain two separate binding sites for Rab-proteins, allowing Micals and EHBPs to bind two Rabs simultaneously. The strong similarity between the two binding sites within one bMRB domain strongly suggests an evolutionarily development via duplication of a common ancestor supersecondary structure element. The bMERB domain has a completely alpha-helical fold consisting of a central helix and N- and C-terminal helices folding back on this central helix.

calponin homology (CH) domain found in the EH domain-binding protein (EHBP) family; The EHBP family includes EHBP1 and EHBP1-like protein (EHBP1L1). EHBP1 is a regulator of endocytic recycling and may play a role in actin reorganization by linking clathrin-mediated endocytosis to the actin cytoskeleton. It may act as an effector of small GTPases, including RAB-10 (Rab10), and play a role in vesicle trafficking. EHBP1 is associated with aggressive prostate cancer and insulin-stimulated trafficking and cell migration. EHBP1L1 may also act as Rab effector protein and play a role in vesicle trafficking. It coordinates Rab8 and Bin1 to regulate apical-directed transport in polarized epithelial cells. Members of this family contain a single copy of the CH domain. CH domains are actin filament (F-actin) binding motifs.

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

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

This domain belongs to the LIM domain family which are found on Mical (molecule interacting with CasL) like proteins; The LIM domain on proteins of unknown function: This domain belongs to the LIM domain family which are found on Mical (molecule interacting with CasL) like proteins. Known members of the Mical-like family includes single LIM domain containing proteins, Mical (molecule interacting with CasL), pollen specific protein SF3, Eplin, xin actin-binding repeat-containing protein 2 (XIRP2), and Ltd-1. The members of this family function mainly at the cytoskeleton and focal adhesions. They interact with transcription factors or other signaling molecules to play roles in muscle development, neuronal differentiation, cell growth, and mobility. 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.

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