CC -!- FUNCTION: Integrin alpha-5/beta-1 (ITGA5:ITGB1) is a receptor for
CC fibronectin. It recognizes the sequence R-G-D in its ligands.
CC ITGA5:ITGB1 acts as a receptor for fibrillin-1 (FBN1) and mediates R-G-
CC D-dependent cell adhesion to FBN1. ITGA5:ITGB1 is a receptor for IL1B
CC and binding is essential for IL1B signaling. ITGA5:ITGB3 is a receptor
CC for soluble CD40LG and is required for CD40/CD40LG signaling (By
CC similarity). {ECO:0000250|UniProtKB:P08648}.
CC -!- SUBUNIT: Heterodimer of an alpha and a beta subunit. The alpha subunit
CC is composed of a heavy and a light chain linked by a disulfide bond.
CC Alpha-5 associates with beta-1.
CC -!- SUBCELLULAR LOCATION: Membrane; Single-pass type I membrane protein.
CC Cell junction, focal adhesion {ECO:0000250|UniProtKB:P08648}. Cell
CC surface {ECO:0000250|UniProtKB:P08648}.
CC -!- SIMILARITY: Belongs to the integrin alpha chain family. {ECO:0000305}.
