| Enzyme Function | FUNCTION: Probable serine lipid hydrolase associated with lipid droplets (By similarity). Appears to lack cholesterol esterase activity (PubMed:27836991). Appears to lack triglyceride lipase activity (PubMed:23525007, PubMed:27836991). Involved in negatively regulating juvenile hormone (JH) and possibly, insulin signaling activities such as triacylglycerols (TAG) storage, and thereby plays a role in the endocrine regulation of organismal growth and survival (PubMed:30917324). Likely functions by enhancing the activity of the JH hydrolase enzymes Jheh1 and Jheh2 (PubMed:30917324). Required for lipid droplet positioning and fat storage (PubMed:23525007). {ECO:0000250|UniProtKB:Q8BVA5, ECO:0000269|PubMed:23525007, ECO:0000269|PubMed:27836991, ECO:0000269|PubMed:30917324}. |

| Subcellular Location | SUBCELLULAR LOCATION: Lipid droplet {ECO:0000269|PubMed:23525007, ECO:0000269|PubMed:27836991}. Endoplasmic reticulum membrane {ECO:0000269|PubMed:23525007}; Multi-pass membrane protein {ECO:0000255}. Note=Localizes to the endoplasmic reticulum in absence of lipid droplets and translocates to lipid droplets upon lipid storage induction. {ECO:0000269|PubMed:23525007}. |
