Peptide Name: JNK1 (185-194) pY185+pT188+pY191
Product Use: This phosphopeptide may be useful as a substrate for screening the phosphatase activity of protein phosphatases. The peptide sequence is located in the protein kinase catalytic domain activation T loop region between subdomains VII and VIII. Y185 phosphorylation stimulates phosphotransferase activity. T188 and Y191 phosphorylation is predicted to be inhibitory to catalytic activity.

Scientific Background: JNK1 (MAPK8) is a protein-serine/threonine kinase of the CMGC group and MAPK family. It is involved in the regulation of several cellular processes, including cell proliferation, differentiation, migration, transformation, and apoptosis, through the JNK/SAP signalling pathway. This pathway is activated by extracellular stimuli such as pro-inflammatory cytokines or physical stress, as well as signals of intracellular stress, such as misfolded proteins in the endoplasmic reticulum. Phosphorylation of T183 and Y185 by either of two dual specificity kinases, MAP2K4 and MAP2K7, increases phosphotransferase activity. It is inhibited by dual specificity phosphatases, such as DUSP1, which target the T183 and Y185 activatory phosphorylation sites.
