Protein

1-phosphatidylinositol 4,5-bisphosphate phosphodiesterase delta-4

Gene

Plcd4

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Hydrolyzes the phosphatidylinositol 4,5-bisphosphate (PIP2) to generate 2 second messenger molecules diacylglycerol (DAG) and inositol 1,4,5-trisphosphate (IP3). DAG mediates the activation of protein kinase C (PKC), while IP3 releases Ca2+ from intracellular stores. Required for acrosome reaction in sperm during fertilization, probably by acting as an important enzyme for intracellular Ca2+ mobilization in the zona pellucida-induced acrosome reaction. May play a role in cell growth. Modulates the liver regeneration in cooperation with nuclear PKC. Overexpression up-regulates the Erk signaling pathway and proliferation. Isoform 4 has no enzyme activity and acts as a negative regulator of phospholipases C, with a preference for PLC-delta family.1 Publication

Present at high level in testis. Also present in brain > skeletal muscle > thyroid gland > stomach > thymus > aorta > heart (at protein level). Highly expressed in regenerating liver. Isoform 4 is weakly expressed compared to other isoforms but is expressed at high level in some neural cells.2 Publications

Domaini

The PDZ-binding motif mediates the interaction with GRIP1.By similarity
The C2 domain mediates pre-localization to the membrane prior to Ca2+ import and non-selective Ca2+-mediated targeting to various cellular membranes.
The PH domain is not a critical determinant of the membrane localization. The PH domain of isoform 4 is necessary and sufficient to inhibit enzyme activity of other PLC-delta enzymes.
