Summaries for PITPNA Gene

Entrez Gene Summary for PITPNA Gene

  • This gene encodes a member of a family of lipid-binding proteins that transfer molecules of phosphatidylinositol or phosphatidylcholine between membrane surfaces. The protein is implicated in phospholipase C signaling and in the production of phosphatidylinositol 3,4,5-trisphosphate (PIP3) by phosphoinositide-3-kinase.[provided by RefSeq, Sep 2009]

GeneCards Summary for PITPNA Gene

PITPNA (Phosphatidylinositol Transfer Protein Alpha) is a Protein Coding gene. Diseases associated with PITPNA include Hereditary Choroidal Atrophy and Partial Central Choroid Dystrophy. Among its related pathways are Developmental Biology and Netrin-1 signaling. GO annotations related to this gene include lipid binding and phosphatidylcholine transporter activity. An important paralog of this gene is PITPNM2.
