Protein attributes

Sequence length	1175 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
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. This form has a role in retina signal transduction.
Catalytic activity	1-phosphatidyl-1D-myo-inositol 4,5-bisphosphate + H(2)O = 1D-myo-inositol 1,4,5-trisphosphate + diacylglycerol.
Cofactor	Calcium.
Tissue specificity	Preferentially expressed in the retina.
Sequence similarities	Contains 1 C2 domain. Contains 1 PI-PLC X-box domain. Contains 1 PI-PLC Y-box domain.
