Protein attributes
| Sequence length | 782 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Calcium-independent phospholipase A2, which catalyzes the hydrolysis of the sn-2 position of glycerophospholipids, PtdSer and to a lower extent PtdCho. Cleaves membrane phospholipids. Ref.2 Ref.11 |
| Catalytic activity | 2-lysophosphatidylcholine + H2O = glycerophosphocholine + a carboxylate. |
| Enzyme regulation | Inhibited by E-6-bromomethylene-3-1-naphthalenyl-2H-tetrahydropyran-2-one (BEL). |
| Subcellular location | Endoplasmic reticulum membrane; Single-pass membrane protein By similarity. Golgi apparatus membrane; Single-pass membrane protein By similarity. Cytoplasm › perinuclear region By similarity Ref.2. |
| Tissue specificity | Expressed in parenchymal tissues including heart, skeletal muscle, placenta, brain, liver and pancreas. Also expressed in bronchial epithelial cells and kidney. Highest expression is observed in skeletal muscle and heart. Ref.1 Ref.2 Ref.10 Ref.11 |
| Sequence similarities | Contains 1 patatin domain. |
| Biophysicochemical properties | pH dependence: Optimum pH is 8.0. |
| Sequence caution | The sequence AAF67630.1 differs from that shown. Reason: Erroneous initiation. The sequence BAA92090.1 differs from that shown. Reason: Erroneous initiation. The sequence EAL24384.1 differs from that shown. Reason: Erroneous gene model prediction. |
