ZAP70 (human)

Overview
ZAP70 a tyrosine kinase of the Syk family. Associates with the T-cell antigen receptor zeta-chain after TCR stimulation. Phosphorylated by Src-family kinases following antigen receptor activation. Plays a role in lymphocyte activation. Note: This description may include information from UniProtKB.
