2.7.11.19 | physiological function |
glycogen phosphorylase kinase (PHK) is a serine/threonine-specific protein kinase that phosphorylates a serine residue in glycogen phosphorylase (PYG), triggering the activation of this latter enzyme that catalyzes the phosphorolytic cleavage of the alpha-1,4 glycosidic linkages of glycogen, releasing glucose-1-phosphate as the reaction product. The glycogen phosphorylase kinase beta-subunit (PHKB) interacts with the C-terminal region of KIAA1199 protein, that is associated with cancer cell migration or invasion and a poor prognosis and with non-syndromic hearing loss. KIAA1199 protein also interacts with glycogen phosphorylase brain form (PYGB) under serum-free conditions. The interaction promotes glycogen breakdown and cancer cell survival.

2.7.11.19 | physiological function |
glycogen phosphorylase, EC 2.4.1.1, exists in two interconvertible forms, GPa (phosphorylated form, high activity) and GPb (nonphosphorylated form, low activity). Phosphorylase kinase catalyses the phosphorylation of GPb and plays a key role in the cascade system for regulating glycogen metabolism |
