Fas (also known as Apo-1 and CD95) is a 40-50 kDa cell surface glycoprotein and a member of the TNF receptor family. Fas is an apotosis signalling molecule that forms the death inducing signalling complex (DISC) upon binding by the Fas ligand trimer on an adjacent cell. The Fas receptor also trimerizes, after which it is internalized and can then bind to the adaptor molecule FADD. FADD facilitates binding of caspase-8. which is activated to induce caspase-8 mediated apoptosis. Fas also plays a role in T cell mediated cytotoxicity and T cell development. Fas is found in the thymus, liver, heart, and ovary, where it is expressed on a minority of resting T and B cells and monocytes. The antagonistic ZB4 clone anti-Fas monoclonal has been used to block the apoptosis-inducing activity of the Anti-Fas CH-11 clone in multiple publications.
