Description

Application

Human ZAP-70 Tyrosine Kinase was used for mapping the phosphorylation sites on LAT (linker for activation of T cells) for investigating the mechanism of activation of signalling proteins in T cells.

Biochem/physiol Actions

ZAP-70 Tyrosine Kinase is a protein belongs to Syk family and is essential for T cell activation. It facilitates the upregulation of Fas ligand in activation-induced T cell apoptosis. Additionally, it also plays a pivotal role in LFA-1-dependent T Cell Migration.

ZAP-70 is protein tyrosine kinase of the Syk family that is localized exclusively to the cytosol of T cells and natural killer cells. It is required for T cell activation. It is activated by Lck-mediated phosphorylation of its tyrosine residues.
