Description

This entry includes patatin-like phospholipase domain-containing proteins 1-5 (PNPLA1-5) from humans and Atgl-1 from Caenorhabditis elegans. They are a group of lipid hydrolases.

Atgl-1 may play a role in the response of the organism to starvation, enhancing hydrolysis of triglycerides and providing free fatty acids to other tissues to be oxidized in situations of energy depletion [PMID: 19052547, PMID: 20176933, PMID: 24120942, PMID: 25202121, PMID: 26083785, PMID: 26098762].

Human PNPLA1 plays a role in glycerophospholipid metabolism [PMID: 22246504]. PNPLA2 catalyses the initial step in triglyceride hydrolysis in adipocyte and non-adipocyte lipid droplets [PMID: 15550674]. PNPLA3 has both triacylglycerol lipase and acylglycerol O-acyltransferase activities [PMID: 15364929].
