Probable serine lipid hydrolase associated with lipid droplets. Appears to lack cholesterol esterase activity. Appears to lack triglyceride lipase activity. Highly expressed in macrophage-rich areas in atherosclerotic lesions, suggesting that it could promote cholesterol ester turnover in macrophages.
Subcellular locations: Lipid droplet, Endoplasmic reticulum
Localizes to the endoplasmic reticulum in absence of lipid droplets and translocates to lipid droplets upon lipid storage induction.
