Glucosidase 2 Subunit Beta (PRKCSH) Human Recombinant Protein

This gene encodes the beta-subunit of glucosidase II, an N-linked glycan-processing enzyme in the endoplasmic reticulum. The encoded protein is an acidic phosphoprotein known to be a substrate for protein kinase C. Mutations in this gene have been associated with the autosomal dominant polycystic liver disease. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2014]

PRKCSH: Regulatory subunit of glucosidase II. Defects in PRKCSH are a cause of polycystic liver disease (PCLD). PCLD is an autosomal dominant disorder and is characterized by the presence of multiple liver cysts of biliary epithelial origin. PCLD is a distinct clinical and genetic entity that can occur independently from autosomal dominant polycystic kidney disease (ADPKD), which in a considerable but uncertain proportion of cases is associated with hepatic cysts. 2 isoforms of the human protein are produced by alternative splicing.
