Datasheet Extract

Synthetic peptide (Human) derived from the region of human Lck that contains tyrosine 192 (based on Swiss Protein database, accession number P06239). The sequence is conserved in human and mouse.

Background Lck (p56lck), a member of the Src family of non-receptor tyrosine protein kinases, is expressed predominantly in T cells. Lck function is critical both for T cell development in the thymus and activation of mature T cells in the periphery by antigen. The activity of Lck is regulated by phosphorylation of multiple sites, including the two conserved tyrosine residues, Tyr-505 (equivalent to Tyr-529 in c-Src) and Tyr-394 (equivalent to Tyr-418 in c-Src). Phosphorylation of Lck Tyr-192 blocks high affinity binding of other proteins to the SH2 domain of Lck, thereby negatively regulating its participation in T cell antigen receptor signalling.
Concentration 0.5 mg/ml
