Protein attributes
| Sequence length | 1693 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | The production of the second messenger molecules diacylglycerol (DAG) and inositol 1,4,5-trisphosphate (IP3) is mediated by calcium-activated phosphatidylinositol-specific phospholipase C enzymes. Ref.1 |
| Catalytic activity | 1-phosphatidyl-1D-myo-inositol 4,5-bisphosphate + H2O = 1D-myo-inositol 1,4,5-trisphosphate + diacylglycerol. |
| Cofactor | Calcium. |
| Subcellular location | |
| Tissue specificity | Expressed in brain and to a lower extent in lung. In brain, it is found in cerebrum, cerebellum and spinal cord. Ref.1 |
| Sequence similarities | Contains 1 C2 domain. Contains 2 EF-hand domains. Contains 1 PH domain. Contains 1 PI-PLC X-box domain. Contains 1 PI-PLC Y-box domain. |
| Sequence caution | The sequence BAB14129.1 differs from that shown. Reason: Erroneous initiation. |
