General annotation (Comments)
| Function | Plays 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. |
| Catalytic activity | A 1,2-diacylglycerol 3-phosphate + H2O = a 1,2-diacyl-sn-glycerol + phosphate. |
| Cofactor | Mg2+ By similarity. |
| Enzyme regulation | Inhibited by N-ethylmaleimide By similarity. |
| Subunit structure | Interacts (via LXXIL motif) with PPARA By similarity. Interacts with PPARGC1A By similarity. Interaction with PPARA and PPARGC1A leads to the formation of a complex that modulates gene transcription By similarity. Interacts with MEF2C By similarity. |
| Subcellular location | Nucleus membrane By similarity. Cytoplasm › cytosol By similarity. Endoplasmic reticulum membrane By similarity. |
| Tissue specificity | Specifically expressed in skeletal muscle. Also abundant in adipose tissue. Lower levels in some portions of the digestive tract. Ref.6 Ref.13 |
| Domain | Contains one Leu-Xaa-Xaa-Ile-Leu (LXXIL), a transcriptional binding motif, which mediates interaction with PPARA By similarity. Contains 1 Asp-Xaa-Asp-Xaa-Thr (DXDXT) motif, a catalytic motif essential for phosphatidate phosphatase activity By similarity. |
| Post-translational modification | Phosphorylated at multiple sites in response to insulin. Phosphorylation is controlled by the mTOR signaling pathway. Phosphorylation is decreased by epinephrine. Phosphorylation may not directly affect the catalytic activity but may regulate the localization. Dephosphorylated by the CTDNEP1-CNEP1R1 complex By similarity. Sumoylated By similarity. |
| Involvement in disease | Myoglobinuria, acute recurrent, autosomal recessive (ARARM) [MIM:268200]: Recurrent myoglobinuria is characterized by recurrent attacks of rhabdomyolysis (necrosis or disintegration of skeletal muscle) associated with muscle pain and weakness and followed by excretion of myoglobin in the urine. Renal failure may occasionally occur. |
| Miscellaneous | May represent a candidate gene for human lipodysytropy syndromes. |
| Sequence similarities | Belongs to the lipin family. |
| Sequence caution | The sequence BAA11505.1 differs from that shown. Reason: Erroneous initiation. |
