 37-190 2.70e-117

calponin homology (CH) domain found in Ras GTPase-activating-like protein IQGAP1; IQ motif containing GTPase activating protein 1 (IQGAP1), also called p195, is a homodimeric protein that is widely expressed among vertebrate cell types from early embryogenesis. It plays a crucial role in regulating the dynamics and assembly of the actin cytoskeleton. It belongs to the IQGAP family, which consists of multi-domain proteins having a calponin-homology (CH) domain which binds F-actin, IQGAP-specific repeats, a single WW domain, four IQ motifs that mediate interactions with calmodulin, and a RasGAP related domain that binds active Rho family GTPases. IQGAP1 negatively regulates Ras family GTPases by stimulating their intrinsic GTPase activity. It lacks GAP activity. Both, IQGAP1 and IQGAP2, specifically bind to Cdc42 and Rac1, but not to RhoA. Despite similarities to part of the sequence of RasGAP, neither IQGAP1 nor IQGAP2 interacts with Ras. IQGAP1 contains a single copy of the CH domain at the N-terminus.

 48-158 1.04e-16

Calponin homology (CH) domain; The CH domain is found in both cytoskeletal proteins and signal transduction proteins. The CH domain is involved in actin binding in some members of the family. However in calponins there is evidence that the CH domain is not involved in its actin binding activity. Most member proteins have from two to four copies of the CH domain, however some proteins such as calponin have only a single copy.

calponin homology (CH) domain found in the IQ motif containing GTPase activating protein family; Members of the IQ motif containing GTPase activating protein (IQGAP) family are associated with the Ras GTP-binding protein and act as essential regulators of cytoskeletal function. There are three known IQGAP family members: IQGAP1, IQGAP2, and IQGAP3. They are multi-domain molecules having a calponin-homology (CH) domain which binds F-actin, IQGAP-specific repeats, a single WW domain, four IQ motifs that mediate interactions with calmodulin, and a RasGAP related domain that binds active Rho family GTPases. IQGAP1 negatively regulates Ras family GTPases by stimulating their intrinsic GTPase activity. It lacks GAP activity. Both IQGAP1 and IQGAP2 specifically bind to Cdc42 and Rac1, but not to RhoA. Despite similarities to part of the sequence of RasGAP, neither IQGAP1 nor IQGAP2 interacts with Ras. IQGAP3 regulates the organization of the cytoskeleton under the regulation of Rac1 and Cdc42 in neuronal cells. The depletion of IQGAP3 is shown to impair neurite or axon outgrowth in neuronal cells with disorganized cytoskeleton.

 47-157 5.97e-28

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).

Calponin homology (CH) domain; The CH domain is found in both cytoskeletal proteins and signal transduction proteins. The CH domain is involved in actin binding in some members of the family. However in calponins there is evidence that the CH domain is not involved in its actin binding activity. Most member proteins have from two to four copies of the CH domain, however some proteins such as calponin have only a single copy.

calponin homology (CH) domain found in LIM domain only protein 7 and similar proteins; This family includes LIM domain only protein 7 (LMO-7) and LIM and calponin homology domains-containing protein 1 (LIMCH1), and similar proteins. LMO-7, also called F-box only protein 20, or LOMP, is a transcription regulator for expression of many Emery-Dreifuss muscular dystrophy (EDMD)-relevant genes. It binds to alpha-actinin and AF6/afadin at adherens junctions for epithelial cell-cell adhesion. LIMCH1 acts as an actin stress fiber-associated protein that activates the non-muscle myosin IIa complex by promoting the phosphorylation of its regulatory subunit MRLC/MYL9. It positively regulates actin stress fiber assembly and stabilizes focal adhesions, and therefore negatively regulates cell spreading and cell migration. Members of this family contain a single copy of the CH domain at the N-terminus. CH domains are actin filament (F-actin) binding motifs.

calponin homology (CH) domain found in VAV1 protein; VAV1 is expressed predominantly in the hematopoietic system and it plays an important role in the development and activation of B and T cells. It is activated by tyrosine phosphorylation to function as a guanine nucleotide exchange factor (GEF) for Rho GTPases following cell surface receptor activation, triggering various effects such as cytoskeletal reorganization, transcription regulation, cell cycle progression, and calcium mobilization. It also serves as a scaffold protein and has been shown to interact with Ku70, Socs1, Janus kinase 2, SIAH2, S100B, Abl gene, ZAP-70, SLP76, and Syk, among others. VAV proteins contain several domains that enable their function: N-terminal calponin homology (CH), acidic, RhoGEF (also called Dbl-homologous or DH), Pleckstrin Homology (PH), C1 (zinc finger), SH2, and two SH3 domains. This model corresponds to the CH domain, an actin-binding domain which is present as a single copy in VAV1 protein.
