PhosphorylaseKinase β-SubunitFragment (420-436) is a peptide fragment (430-436) derived from the β-Subunit of phosphorylasekinase. Phosphorylasekinase, a serine threonine-specific protein kinase, plays a crucial role in the activation of glycogen phosphorylase for the release of glucose-1-phosphate from glycogen[1].
This Mitogen-activated protein kinase (MAP kinase) fragment has a peptide sequence of Lys-Tyr-Ile-His-Ser-Ala-Asn-Val-Leu. The MAP kinases are serine threonine-specific protein kinases belonging to the CMGC (CDK MAPK GSK3 CLK) kinase group.
