Phosphorylase b kinase gamma catalytic chain, skeletal muscle/heart isoform (PHKG1)

Catalytic subunit of the phosphorylase b kinase (PHK), which mediates the neurological and hormonal regulation of glycogen breakdown (glycogenolysis) by phosphorylating and thereby activating glycogen phosphorylase. In vitro, phosphorylates PYGM, TNNI3, MAPT/TAU, GAP43 and NRGN/RC3 (By similarity).
