CD103 (ITGAE, Integrin alpha E) is molecule that is expressed on mucosa-associated T lymphocytes and activated cells and on subet of TGF beta -1 cells. In particular, CD103 includes a 150kDa alpha chain and a 120kDa beta chain. CD103 is expressed by 0.5 to 2% of resting lymphocytes in peripheral blood and lymphoid organs. CD103 antibody stains a few bone marrow cells and, rarely, peripheral blood lymphocytes. CD103 is part of the integrin family which are heterodimeric integral membrane proteins composed of an alpha chain and a beta chain. ITGAE encodes an I-domain-containing alpha integrin that undergoes post-translational cleavage in the extracellular domain, yielding disulfide-linked heavy and light chains. In combination with the beta 7 integrin, CD103 protein forms the E-cadherin binding integrin known as the human mucosal lymphocyte-1 antigen. CD103 is preferentially expressed in human intestinal intraepithelial lymphocytes (IEL), and in addition to a role in adhesion, it may serve as an accessory molecule for IEL activation. Diseases associated with CD103 dysfunction include hairy cell leukemia and splenic marginal zone lymphoma.
