Cell 0:0-0(2013). CC -!- FUNCTION: Key regulator of the integrin-mediated cell-matrix CC interaction signaling by binding to the ITGB1 cytoplasmic tail and CC preventing the activation of integrin alpha-5/beta-1 (heterodimer CC of ITGA5 and ITGB1) by talin or FERMT1. Plays a role in cell CC proliferation, differentiation, spreading, adhesion and migration CC in the context of mineralization and bone development and CC angiogenesis. Stimulates cellular proliferation in a fibronectin- CC dependent manner. Involved in the regulation of beta-1 integrin- CC containing focal adhesion (FA) site dynamics by controlling its CC assembly rate during cell adhesion; inhibits beta-1 integrin CC clustering within FA by directly competing with talin TLN1, and CC hence stimulates osteoblast spreading and migration in a CC fibronectin-and/or collagen-dependent manner. Acts as a guanine CC nucleotide dissociation inhibitor (GDI) by regulating Rho family CC GTPases during integrin-mediated cell matrix adhesion; reduces the CC level of active GTP-bound form of both CDC42 and RAC1 GTPases upon CC cell adhesion to fibronectin. Stimulates the release of active CC CDC42 from the membranes to maintain it in an inactive cytoplasmic CC pool. Participates in the translocation of the Rho-associated CC protein kinase ROCK1 to membrane ruffles at cell leading edges of CC the cell membrane, leading to an increase of myoblast cell CC migration on laminin. Plays a role in bone mineralization at a CC late stage of osteoblast differentiation; modulates the dynamic CC formation of focal adhesions into fibrillar adhesions, which are CC adhesive structures responsible for fibronectin deposition and CC fibrillogenesis. Plays a role in blood vessel development; acts as CC a negative regulator of angiogenesis by attenuating endothelial CC cell proliferation and migration, lumen formation and sprouting CC angiogenesis by promoting AKT phosphorylation and inhibiting CC ERK1/2 phosphorylation through activation of the Notch signaling CC pathway. Promotes transcriptional activity of the MYC promoter.

CC -!- SUBUNIT: Interacts (via N-terminus and PTB domain) with ROCK1 (By CC similarity). Found in a complex, at least composed of ITGB1BP1, CC KRIT1 and RAP1A. Interacts (via C-terminal region) with ITGB1 (via CC C-terminal cytoplasmic tail); the interaction prevents talin TLN1 CC binding to ITGB1 and KRIT1 and ITGB1 compete for the same binding CC site. Interacts with KRIT1 (via N-terminal NPXY motif); the CC interaction induces the opening conformation of KRIT1 and KRIT1 CC and ITGB1 compete for the same binding site. Isoform 2 does not CC interact with ITGB1. Interacts with CDC42 (GTP- or GDP-bound CC form); the interaction is increased with the CDC42-membrane bound CC forms and prevents both CDC42 activation and cell spreading. CC Interacts (via C-terminal domain region) with NME2. Interacts with CC FERMT2 and RAC1. {ECO:0000250, ECO:0000269|PubMed:11741838, CC ECO:0000269|PubMed:11741908, ECO:0000269|PubMed:11807099, CC ECO:0000269|PubMed:11854171, ECO:0000269|PubMed:11919189, CC ECO:0000269|PubMed:12473654, ECO:0000269|PubMed:17916086, CC ECO:0000269|PubMed:21768292, ECO:0000269|PubMed:9281591, CC ECO:0000269|PubMed:9867804, ECO:0000269|Ref.19}.

Cytoplasm. Cytoplasm, cytoskeleton CC {ECO:0000250}. Cell membrane {ECO:0000250}. Cell projection, CC lamellipodium. Cell projection, ruffle. Note=Nucleocytoplasmic CC shuttling protein; shuttles between nucleus and cytoplasm in a CC integrin-dependent manner; probably sequestered in the cytosol by CC ITGB1. Its localization is dependent on the stage of cell CC spreading on fibronectin; cytoplasmic in case of round cells, CC corresponding to the initial step of cell spreading, or nuclear in CC case of well spread cells. Colocalizes with ROCK1 and NME2 at CC beta-1 integrin engagement sites. Together with ITGB1 and NME2 is CC recruited to beta-1 integrin-rich peripheral ruffles and CC lamellipodia during initial cell spreading on fibronectin and/or CC collagen.
