Facts about Integrin beta-1-binding protein 1.
Stimulates cellular proliferation in a fibronectin- dependent way. Involved in the regulation of beta-1 integrin- containing focal adhesion (FA) site dynamics by controlling its assembly speed during cell adhesion; inhibits beta-1 integrin clustering within FA by directly competing with talin TLN1, and hence stimulates osteoblast spreading and migration in a fibronectin-and/or collagen-dependent manner.

Expressed in endothelial cells and fibroblasts (at protein level). Ubiquitously expressed. Expressed in intestine, colon, testis, ovary, thymus, spleen and prostate.
Nucleus. Cytoplasm. Cytoplasm, cytoskeleton. Cell membrane. Cell projection, lamellipodium. Cell projection, ruffle. Nucleocytoplasmic shuttling protein; shuttles between nucleus and cytoplasm in a integrin-dependent manner; probably sequestered in the cytosol by ITGB1. Its localization is dependent on the stage of cell spreading on fibronectin; cytoplasmic in case of round cells, corresponding to the initial step of cell spreading, or nuclear in case of well spread cells. Colocalizes with ROCK1 and NME2 at beta-1 integrin engagement sites. Together with ITGB1 and NME2 is recruited to beta-1 i
