背景介绍 PHKG2 is the hepatic and testis isoform of the gamma subunit of phosphorylase kinase. PHKG2 gene contains 10 exons and spans 9.5 kb and maps to chromosome 16p12.1-p11.2 (1). Deficiency of PHK, a regulatory enzyme of glycogen metabolism, is responsible for 25% of all cases of glycogen storage disease and is genetically and clinically heterogeneous. Mutations in the PHKG2 gene lead to autosomal liver-specific PHK deficiency (glycogen storage disease IXc) and an increased risk of cirrhosis and at least 11 PHKG2 mutations have been identified to date (2). 产品介绍 Recombinant human PHKG2, full length, with N-terminal GST-tag, expressed in Sf9 insect cells via a baculovirus expression system.
