General annotation (Comments)

Function

Integrin alpha-9/beta-1 is a receptor for VCAM1, cytotactin and osteopontin. It recognizes the sequence A-E-I-D-G-I-E-L in cytotactin.

Subunit structure

Heterodimer of an alpha and a beta subunit. Alpha-9 associates with beta-1.

Subcellular location

Membrane; Single-pass type I membrane protein.

Tissue specificity

In airway epithelium, in the basal layer of squamous epithelium, and in smooth muscle, skeletal muscle, and hepatocytes. Abundantly expressed in fetal lung and lung cancers.

Induction

Up-regulated in small cell lung cancers (SCLC).

Sequence similarities

Belongs to the integrin alpha chain family.

Contains 7 FG-GAP repeats.
