Phospholipase involved in maintaining the lipid droplet morphology (PubMed:25014274). Has phospholipase activity with broad substrate specificity, acting on glycerophospholipids phosphatidylethanolamine (PE), phosphatidic acid (PA), phosphatidycholine (PC) and phosphatidylserine (PS), primarily at sn-2 position (PubMed:25014274). It can later remove fatty acids from the sn-1 position of the produced lysophospholipids such as lysophosphatidylethanolamine (LPE) (PubMed:25014274). Shows also activity toward phosphatidylglycerol, but, in contrast to what was observed with the other phospholipids tested, prefers the sn-1 position (PubMed:25014274). a 1,2-diacyl-sn-glycero-3-phosphoethanolamine + H2O = a 1-acyl-sn-glycero-3-phosphoethanolamine + a fatty acid + H(+) a 1-acyl-sn-glycero-3-phosphoethanolamine + H2O = a fatty acid + H(+) + sn-glycero-3-phosphoethanolamine a 1,2-diacyl-sn-glycero-3-phosphate + H2O = a 1-acyl-sn-glycero-3-phosphate + a fatty acid + H(+) a 1,2-diacyl-sn-glycero-3-phosphocholine + H2O = a 1-acyl-sn-glycero-3-phosphocholine + a fatty acid + H(+) a 1,2-diacyl-sn-glycero-3-phospho-L-serine + H2O = a 1-acyl-sn-glycero-3-phospho-L-serine + a fatty acid + H(+) a 1,2-diacyl-sn-glycero-3-phosphoglycerol + H2O = a 2-acyl-sn-glycero-3-phosphoglycerol + a fatty acid + H(+) a 1-(9Z-octadecenoyl)-2-acyl-sn-glycero-3-phosphocholine + H2O = 1-(9Z-octadecenoyl)-sn-glycero-3-phosphocholine + a fatty acid + H(+) a 1-(9Z-octadecenoyl)-2-acyl-sn-glycero-3-phosphoglycerol + H2O = (9Z)-octadecenoate + a 2-acyl-sn-glycero-3-phosphoglycerol + H(+) an N-aryl-1,2-dihexadecanoyl-sn-glycero-3-phosphoethanolamine + H2O = an N-aryl-1-hexadecanoyl-sn-glycero-3-phosphoethanolamine + H(+) + hexadecanoate a 1-(9Z-octadecenoyl)-2-acyl-sn-glycero-3-phosphate + H2O = 1-(9Z-octadecenoyl)-sn-glycero-3-phosphate + a fatty acid + H(+) 1,2-dihexadecanoyl-sn-glycero-3-phosphoethanolamine + H2O = 1-hexadecanoyl-sn-glycero-3-phosphoethanolamine + H(+) + hexadecanoate Expression is up-regulated by the transcription factor RPN4. Leads to an altered morphology of lipid droplets with a smaller size. Present with 1210 molecules/cell in log phase SD medium. Belongs to the putative lipase ROG1 family.
