Rabbit anti-Human PHKG2 Polyclonal Antibody

Uniprot Id

P15735

Target Species

Human

Target Name

PHKG2

Target Full Name

Phosphorylase b kinase gamma catalytic chain, liver/testis isoform

Target Function

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.

Target Involvement

Glycogen storage disease 9C (GSD9C)

Target Protein Families

Protein kinase superfamily, CAMK Ser/Thr protein kinase family

Target Synonyms

PHKG2Phosphorylase b kinase gamma catalytic chain; liver/testis isoform; PHK-gamma-LT; PHK-gamma-T; EC 2.7.11.19; PSK-C3; Phosphorylase kinase subunit gamma-2

Target Background

Phosphorylase kinase is a polymer of 16 subunits, four each of alpha, beta, gamma and delta. The alpha subunit includes the skeletal muscle and hepatic isoforms, encoded by two different genes. The beta subunit is the same in both the muscle and hepatic isoforms, and encoded by one gene. The gamma subunit also includes the skeletal muscle and hepatic isoforms, and the hepatic isoform is encoded by this gene. The delta subunit is a calmodulin and can be encoded by three different genes. The gamma subunits contain the active site of the enzyme, whereas the alpha and beta subunits have regulatory functions controlled by phosphorylation. The delta subunit mediates the dependence of the enzyme on calcium concentration. Mutations in this gene cause glycogen storage disease type 9C, also known as autosomal liver glycogenosis. Alternatively spliced transcript variants encoding different isoforms have been identified in this gene.
