Vascular cell adhesion protein 1 (VCAM1)

Significant in cell-cell recognition. Appears to work in leukocyte-endothelial cell adhesion.

Interacts with integrin alpha-4/beta-1 (ITGA4/ITGB1) on leukocytes, and mediates both adhesion and signal transduction. The VCAM1/ITGA4/ITGB1 interaction may play a pathophysiologic role both in immune responses and in leukocyte emigration to sites of inflammation.
