|Detection of Integrin alpha 4/CD49d in B16‑F1 Mouse Cell Line by Flow Cytometry. B16‑F1 mouse melanoma cell line was stained with Rat Anti-Mouse Integrin alpha 4/CD49d APC‑conjugated Monoclonal Antibody (Catalog # FAB2450A, filled histogram) or isotype control antibody (Catalog # IC006A, open histogram).

Integrin alpha 4, also known as CD49d and VLA sunbunit alpha, associates with either Integrin beta 1 or beta 7 subunits to form heterodimers that serve as receptors for fibronectin and VCAM-1. Integrin alpha 4 beta 1 is expressed on peripheral lymphocytes, thymocytes, and monocytes, while Integrin alpha 4 beta 7 is expressed on peripheral lymphocytes and a small subset of thymocytes. On T cells, the alpha 4 subunit may contribute to cytotoxic activity. Over amino acids 34-976, mouse Integrin alpha 4 shares 85% amino acid sequence identity to human Integrin alpha 4.
