CD49a

a type I transmembrane protein present on activated T cells, B cells, monocytes, neurovascular endothelium, and smooth muscle that forms a receptor for collagen and laminin; expressed on melanomas.

ITGA1

A gene on chromosome 5q11.2 that encodes an integrin alpha chain protein which, like all integrins, forms a heterodimer with a beta chain, thereby participating in an array of cell-cell and cell-matrix interactions, playing a major role in cell migration, organ and tissue development and differentiation. The alpha-1 beta-1 heterodimer forms a cell surface receptor for collagen and laminin, is involved in cell-cell adhesion and may play a role in inflammation and fibrosis.
