PHKG2 (P15735) - Overview - Molecular Target Synopsis


PHKG2, Phosphorylase b kinase gamma catalytic chain, liver/testis isoform
Enzyme Classification
UniProt P15735

Also Known as PHKG2_HUMAN, PHKG2

Catalytic subunit of the phosphorylase b kinase (PHK), which mediates the neural and hormonal regulation of glycogen breakdown (glycogenolysis) by phosphorylating and thereby activating glycogen phosphorylase. May regulate glycogeneolysis in the testis. In vitro, phosphorylates PYGM. Hexadecamer of 4 heterotetramers, each composed of alpha, beta, gamma, and delta subunits. Alpha (PHKA1 or PHKA2) and beta (PHKB) are regulatory subunits, gamma (PHKG1 or PHKG2) is the catalytic subunit, and delta is calmodulin.
