Protein

Patatin-like phospholipase domain-containing protein 2

Gene

Pnpla2

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Catalyzes the initial step in triglyceride hydrolysis in adipocyte and non-adipocyte lipid droplets. Also has acylglycerol transacylase activity. May act coordinately with LIPE/HLS within the lipolytic cascade. Regulates adiposome size and may be involved in the degradation of adiposomes. May play an important role in energy homeostasis. 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.By similarity

Catalytic activityi

Triacylglycerol + H2O = diacylglycerol + a carboxylate.

Pathwayi: triacylglycerol degradation

This protein is involved in the pathway triacylglycerol degradation, which is part of Glycerolipid metabolism.

Interactioni

Subunit structurei

Interacts with ABHD5; this association stimulates PNPLA2 triglyceride hydrolase activity (By similarity). Interacts with SERPINF1; interacts at one site of interaction (By similarity). Despite a colocalization in lipid droplets, it probably does not interact with PLIN (By similarity). Interacts with PLIN5; prevents interaction with ABHD5 (PubMed:23408028, PubMed:24303154). Interacts with FAF2 (By similarity).By similarity2 Publications

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
