Summaries for PGAP1 Gene

Entrez Gene Summary for PGAP1 Gene

  • The protein encoded by this gene functions early in the glycosylphosphatidylinositol (GPI) biosynthetic pathway, catalyzing the inositol deacylation of GPI. The encoded protein is required for the production of GPI that can attach to proteins, and this may be an important factor in the transport of GPI-anchored proteins from the endoplasmic reticulum to the Golgi. Defects in this gene are a cause of mental retardation, autosomal recessive 42. [provided by RefSeq, Mar 2016]

GeneCards Summary for PGAP1 Gene

PGAP1 (Post-GPI Attachment To Proteins 1) is a Protein Coding gene. Diseases associated with PGAP1 include Mental Retardation, Autosomal Recessive 42 and Autosomal Recessive Spastic Paraplegia Type 67. Among its related pathways are Post-translational modification- synthesis of GPI-anchored proteins and Metabolism of proteins. GO annotations related to this gene include hydrolase activity, acting on ester bonds and phosphoric ester hydrolase activity.

UniProtKB/Swiss-Prot for PGAP1 Gene

  • Involved in inositol deacylation of GPI-anchored proteins. GPI inositol deacylation may important for efficient transport of GPI-anchored proteins from the endoplasmic reticulum to the Golgi (By similarity).
