The clone C-D12, a mouse monoclonal antibody selectively binds with the 70kd tyrosine phosphoprotein known as ZAP-70 which is usually associated with the ζ-chain CD3-receptor-associated protein tyrosine kinase (PTK). It is a member of the Syk family that is localized exclusively to the cytosol of T cells and natural killer (NK) cells and is required for their cellular activation. It is generally considered the T-lymphocyte counterpart of Syk, a B-cell receptor (BCR)-associated kinase that belongs to the same PTK family and plays a similar role in the antigen receptor signaling in the B-lineage cells. It facilitates the upregulation of Fas ligand in activation-induced T cell apoptosis. ZAP-70 expression plays an important role in the clinical diagnosis of various types of hematologic malignancies.
