ZAP70 (Zeta-chain-associated protein kinase-70) is a cytosolic tyrosine kinase expressed in immune cells such as T cells, NK cells, and a subset of B cells. It is recruited by the T Cell Receptor (TCR) upon activation by antigen binding to regulate gene expression and immune cell proliferation. Overexpression of ZAP70 has been observed in B cell malignancies, while patients with defects in ZAP70 have no functional T cells. Malfunctioning of ZAP70 appears to be involved in the onset of autoimmune diseases. ZAP70 is a close homolog to tyrosine kinase SYK, also involved in immune responses.
