Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0009454
UniProt IDP19320
Primary gene name(s)VCAM1
Synonym gene name(s)L1CAM
Protein nameVascular cell adhesion protein 1
Protein functionImportant in cell-cell recognition. Appears to function 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.
Subcellular locationMembrane;
Single-pass type I membrane protein.
