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.

Unit Definition

Activation-induced cell death (AICD) is initiated by the TCR-dependent up-regulation of Fas ligand (FasL) mRNA. The subsequently generated soluble or cell-associated FasL gene products bind Fas, leading to apoptosis of the T cells. Although TCR stimulation is essential to initiate

The processes of T-cell development and activation employ similar immature and mature receptors as well as similar signal transduction pathways to achieve different outcomes. Many signaling molecules are shared between the receptor signaling pathways, including two families of cytoplasmic protein
