CD49d, a member of the integrin family of extracellular matrix and cell adhesion molecules, is the integrin α4 chain. CD49d associates noncovalently with CD29, the integrin β1 subunit, to form the α4β1 very late antigen-4 (VLA-4) heterodimer. Integrin α4 can also associate with integrin β7 to form the α4β7 heterodimer. It is expressed on most leukocytes with the possible exception of neutrophils. VLA-4 mediates leukocyte binding to CD106 (VCAM-1) and is involved in the migration of leukocytes from blood to tissue at sites of inflammation. VLA-4 can also provide a costimulatory signal to T cells for activation and proliferation. The α4β7 integrin heterodimer is expressed on a small subpopulation of thymocytes, most lymph node T and B lymphocytes, NK cells, and eosinophils. Integrin α4β7 also binds to fibronectin and VCAM-1.
