Protein Information (annotations from UniProt)

Database IDHIV0001642
UniProt IDQ14693
Primary gene name(s)LPIN1
Synonym gene name(s)KIAA0188
Protein namePhosphatidate phosphatase LPIN1
Protein functionPlays important roles in controlling the metabolism of fatty acids at differents levels. Acts as a magnesium-dependent phosphatidate phosphatase enzyme which catalyzes the conversion of phosphatidic acid to diacylglycerol during triglyceride, phosphatidylcholine and phosphatidylethanolamine biosynthesis in the reticulum endoplasmic membrane. Acts also as a nuclear transcriptional coactivator for PPARGC1A/PPARA to modulate lipid metabolism gene expression, By similarity. Is involved in adipocyte differentiation. May also be involved in mitochondrial fission by converting phosphatidic acid to diacylglycerol, By similarity. {ECO:0000250}.
Subcellular locationNucleus membrane {ECO:0000250}. Cytoplasm, cytosol {ECO:0000250}. Endoplasmic reticulum membrane {ECO:0000250}.
