General annotation (Comments)
| Function | The production of the second messenger molecules diacylglycerol (DAG) and inositol 1,4,5-trisphosphate (IP3) is mediated by activated phosphatidylinositol-specific phospholipase C enzymes. |
| Catalytic activity | 1-phosphatidyl-1D-myo-inositol 4,5-bisphosphate + H2O = 1D-myo-inositol 1,4,5-trisphosphate + diacylglycerol. |
| Tissue specificity | Expressed in neuronal cell bodies of the optic lobe, central brain, and thoracic ganglia in adults, and the brain of larvae. Ref.1 |
| Sequence similarities | Contains 1 C2 domain. Contains 1 PI-PLC X-box domain. Contains 1 PI-PLC Y-box domain. |
