Summaries for GYG2 Gene

Entrez Gene Summary for GYG2 Gene

  • This gene encodes a member of the the glycogenin family. Glycogenin is a self-glucosylating protein involved in the initiation reactions of glycogen biosynthesis. A gene on chromosome 3 encodes the muscle glycogenin and this X-linked gene encodes the glycogenin mainly present in liver; both are involved in blood glucose homeostasis. This gene has a short version on chromosome Y, which is 3' truncated and can not make a functional protein. Multiple alternatively spliced transcript variants encoding different isoforms have been identified.[provided by RefSeq, May 2010]

GeneCards Summary for GYG2 Gene

GYG2 (Glycogenin 2) is a Protein Coding gene. Diseases associated with GYG2 include Glycogen Storage Disease Type 0. Among its related pathways are Glycosaminoglycan metabolism and Diseases of metabolism. GO annotations related to this gene include transferase activity, transferring glycosyl groups and glycogenin glucosyltransferase activity. An important paralog of this gene is GYG1.
