Function

Integrin alpha-1/beta-1 is a receptor for laminin and collagen. It recognizes the proline-hydroxylated sequence G-F-P-G- E-R in collagen. Involved in anchorage-dependent, negative regulation of EGF-stimulated cell growth. {ECO:0000269PubMed:15592458}.

Subcellular Localization

Membrane {ECO:0000250}; Single-pass type I membrane protein {ECO:0000250}.
