CIB1 Summary & Protein Information

CIB1 Background

Subunit structure: Monomer. Interacts with MYO1C. Interacts (via C-terminal region) with PPP3R1 and CACNA1C; the interactions increase upon cardiomyocytes hypertrophy (By similarity). Interacts with the heterodimeric integrin alpha-IIb/beta3 (ITGA2B-ITGB3). Interacts with ITGA2B (via cytoplasmic domain); the interaction is direct and calcium-dependent. Interacts with the protein kinases PLK2/SNK and PRKDC (via the region immediately upstream of the kinase domain). Interacts with PLK3; the interaction inhibits PLK3 kinase activity. Interacts with PSEN2. Interacts (via C-terminus) with F8. Interacts with NBR1 (via C-terminus). Interacts with FEZ1 (via C-terminus). Interacts with UBR5 (via C-terminus); the interaction is sensitive to DNA damage, and may target CIB1 for ubiquitin-mediated degradation. Interacts with IFI6. Interacts with BCL2. Interacts with ITPR3; the interaction occurs in a calcium-dependent manner. Interacts with PTK2/FAK1. Interacts with MAP3K5; the interaction inhibits MAP3K5 activation by phosphorylation, and its subsequent interaction with TRAF2. Isoform 2 interacts with PRKD2 (via N-terminal AP-rich region), PTK2/FAK1 and PAK1. Interacts with TAS1R2 (via C-terminus); the interaction is independent of the myristoylation state of CIB1. Interacts (via C-terminal region) with STMN2 (via the N-terminal region); the interaction is direct, occurs in a calcium-dependent manner and attenuates the STMN2-induced neurite outgrowth inhibition. Interacts with SPHK1, the interaction occurs in a calcium-dependent manner. Interacts with ITGA2B (via C-terminal cytoplasmic tail); the interaction occurs upon platelet aggregation and is stabilized/increased in a calcium and magnesium-dependent manner. Interacts with PAK1 (via N-terminal region); the interaction is direct and occurs in a calcium-dependent manner. Interacts with RAC3 (via C-terminal region); the interaction induces their association with the cytoskeleton upon alpha-IIb/beta3 integrin-mediated adhesion. Interacts with ITGA5 and ITGAV. {ECO:0000250, ECO:0000269|PubMed:10366599, ECO:0000269|PubMed:10477286, ECO:0000269|PubMed:11323029, ECO:0000269|PubMed:11756406, ECO:0000269|PubMed:11856312, ECO:0000269|PubMed:12011095, ECO:0000269|PubMed:12023286, ECO:0000269|PubMed:12881299, ECO:0000269|PubMed:14992593, ECO:0000269|PubMed:15475008, ECO:0000269|PubMed:15574431, ECO:0000269|PubMed:15685448, ECO:0000269|PubMed:15883187, ECO:0000269|PubMed:15933764, ECO:0000269|PubMed:16061695, ECO:0000269|PubMed:16418530, ECO:0000269|PubMed:16723353, ECO:0000269|PubMed:18627437, ECO:0000269|PubMed:19388079, ECO:0000269|PubMed:19805025, ECO:0000269|PubMed:19854831, ECO:0000269|PubMed:20473878, ECO:0000269|PubMed:20951827, ECO:0000269|PubMed:21215777, ECO:0000269|PubMed:21264284, ECO:0000269|PubMed:21388953, ECO:0000269|PubMed:22283712, ECO:0000269|PubMed:22779914, ECO:0000269|PubMed:23503467, ECO:0000269|PubMed:24011356, ECO:0000269|PubMed:9030514, ECO:0000269|PubMed:9372844}.

Tissue specificity: Detected in platelets and in cell lines of megakaryocytic and erythrocytic lineages. Both isoform 1 and isoform 2 are detected in various cancer cell lines, with isoform 2 being the predominant form (at protein level). Ubiquitously expressed. {ECO:0000269|PubMed:10477286, ECO:0000269|PubMed:11856312, ECO:0000269|PubMed:23503467, ECO:0000269|PubMed:9030514, ECO:0000269|PubMed:9372844}.
