General annotation (Comments)

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.

Subunit structure

Heterodimer of an alpha and a beta subunit. Alpha-1 associates with beta-1. Interacts with RAB21 By similarity.

Subcellular location

Membrane; Single-pass type I membrane protein.

Domain

The integrin I-domain (insert) is a VWFA domain. Integrins with I-domains do not undergo protease cleavage.

Sequence similarities

Belongs to the integrin alpha chain family.

Contains 7 FG-GAP repeats.

Contains 1 VWFA domain.
