NB100-64903 recognizes CD49d, also known as Integrin alpha 4, which associates with either CD29 (integrin beta 1) or integrin beta 7. CD49d is a 150kD molecule, which may be cleaved to 80kD and 70kD fragments. It is expressed by lymphocytes, monocytes, eosinophils and thymocytes. VLA-4 mediates cell adhesion to VCAM-1 and fibronectin. 44H6 induces homotypic aggregation.

Background: Integrin alpha 4/CD49d

VLA-4 is a cell surface heterodimer in the integrin superfamily of adhesion receptors. Anti-VLA-4 antibodies inhibited cytolytic T cell activity, with inhibitory activity directed against the effector T cells rather than their targets. Thus, whereas other VLA receptors appear to mediate cell--matrix interactions, VLA-4 may have a cell--cell adhesion function. Alpha 4 stands apart from all other known integrin alpha subunit sequences because (i) alpha 4 has neither an inserted I-domain, nor a disulfide-linked C-terminal fragment, (ii) its sequence is the most unique and (iii) only alpha 4 has a potential protease cleavage site, near the middle of the coding region, which appears responsible for the characteristic 80,000 and 70,000 Mr fragments of alpha 4 (1). Unlike any other integrin alpha subunit, the intact (150 kDa) alpha 4 subunit of VLA-4 can sometimes be cleaved into two noncovalently associated fragments (80 and 70 kDa) (2). The VLA-4 integrins are indispensable for embryogenesis, haematopoiesis and immune responses, possibly because alpha4 regulates cellular functions differently from other integrins through its cytoplasmic tail (3).
