Previous GeneCards Identifiers for PLA2G4C Gene
This gene encodes a protein which is a member of the phospholipase A2 enzyme family which hydrolyzes glycerophospholipids to produce free fatty acids and lysophospholipids, both of which serve as precursors in the production of signaling molecules. The encoded protein has been shown to be a calcium-independent and membrane bound enzyme. Multiple transcript variants encoding different isoforms have been found for this gene.

UniProtKB/Swiss-Prot Summary for PLA2G4C Gene
Calcium-independent phospholipase, lysophospholipase and O-acyltransferase involved in phospholipid remodeling with implications in endoplasmic reticulum membrane homeostasis and lipid droplet biogenesis (PubMed:19501189, PubMed:9705332, PubMed:10085124, PubMed:10358058, PubMed:28336330). Preferentially hydrolyzes the ester bond of the fatty acyl group attached at the sn-2 position of phospholipids with choline and ethanolamine head groups, producing lysophospholipids that are used in deacylation-reacylation cycles (PubMed:19501189, PubMed:9705332, PubMed:10085124, PubMed:10358058, PubMed:28336330). Transfers the sn-1 fatty acyl from one lysophospholipid molecule to the sn-2 position of another lysophospholipid to form diacyl, alkylacyl and alkenylacyl glycerophospholipids. Cleaves ester bonds but not alkyl or alkenyl ether bonds at sn-1 position of lysophospholipids (PubMed:19501189, PubMed:15944408). Catalyzes sn-2 fatty acyl transfer from phospholipids to the sn-2 position of 1-O-alkyl or 1-O-alkenyl lysophospholipids with lower efficiency (PubMed:19501189, PubMed:15944408). In response to dietary fatty acids, may play a role in the formation of nascent lipid droplets from the endoplasmic reticulum likely by regulating the phospholipid composition of these organelles (PubMed:28336330).
(Microbial infection) May play a role in replication and assembly of human hepatitis C virus (HCV) (PubMed:23015700, PubMed:28336330). In response to HCV infection, promotes remodeling of host endoplasmic reticulum membranes to form organelle-like structures called membranous web, where HCV replication occur (PubMed:23015700). Can further mediate translocation of replication complexes to lipid droplets to enable virion assembly (PubMed:23015700, PubMed:28336330).
(Microbial infection) May facilitate human T-lymphotropic virus type 1 (HTLV-1) infection by promoting leukotriene B4 (LTB4) biosynthesis. LTB4 acts as a chemoattractant for HTLV-1-infected CD4-positive T cells and favors cell to cell viral transmission.
Phospholipases are a group of enzymes that hydrolyze phospholipids into fatty acids and other lipophilic molecules. There are four major classes; phospholipase A, phospholipase B, phosphoinositide-specific phospholipase C and phospholipase D.
