| EC Number | 3.1.1.3 |
| Enzyme Function | FUNCTION: Serine hydrolase required for the maintenance of steady state level of non-polar and polar lipids of lipid droplets and thus plays a role in maintaining the lipids homeostasis (PubMed:21478434). Exhibits both esterase and triacylglycerol lipase activity (PubMed:21478434). {ECO:0000269|PubMed:21478434}. |
