Protein attributes

Sequence length	1095 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 activated phosphatidylinositol-specific phospholipase C enzymes. Essential component of the phototransduction pathway. Ref.1
Catalytic activity	1-phosphatidyl-1D-myo-inositol 4,5-bisphosphate + H2O = 1D-myo-inositol 1,4,5-trisphosphate + diacylglycerol.
Subunit structure	Interacts with inaD.
Tissue specificity	Abundantly expressed in the adult retina. Ref.1
Disruption phenotype	Flies have no photoreceptor potential, their eyes lack phospholipase C (PLC) activity and they are completely blind. Ref.1
Sequence similarities	Contains 1 C2 domain. Contains 1 PI-PLC X-box domain. Contains 1 PI-PLC Y-box domain.
Caution	3D structural studies (Ref.6) were performed with a synthetic heptapeptide that contained Cys, corresponding to position 1094, therefore the detected disulfide bridge is an artifact.
