phosphorylase kinase gamma subunit 2 (phosphorylase b kinase gamma catalytic chain testis/liver isoform, PHKG2, S/T kinase PSK-C3, PSK-C3)

Function

• catalyzes the phosphorylation of Ser in substrates, including troponin I
• may regulate glycogeneolysis in testis

Structure

• belongs to the protein kinase superfamily, CAMK Ser/Thr protein kinase family
• contains 1 protein kinase domain

Expression

mRNA abundant in adult testis

Pathology

• defects in PHKG2 are a cause of glycogen storage disease type 9C

More general terms

• phosphorylase kinase gamma

Component of

• phosphorylase kinase
