Comment typeDescription
Catalytic Activity1-phosphatidyl-1D-myo-inositol 4,5- bisphosphate + H(2)O = 1D-myo-inositol 1,4,5-trisphosphate + diacylglycerol.
CofactorName=Ca(2+); Xref=ChEBI:CHEBI:29108;
FunctionThe production of the second messenger molecules diacylglycerol (DAG) and inositol 1,4,5-trisphosphate (IP3) is mediated by activated phosphatidylinositol-specific phospholipase C enzymes. Required for secondary responses to abscisic acid signals. {ECO:0000269|PubMed:11340187, ECO:0000269|PubMed:7732004, ECO:0000269|Ref.7}.
InductionBy abscisic acid, osmotic stress and environmental stresses such as dehydration, salinity and low temperature. {ECO:0000269|PubMed:7732004, ECO:0000269|Ref.7}.
SimilarityContains 1 C2 domain. {ECO:0000255|PROSITE- ProRule:PRU00041}.
SimilarityContains 1 EF-hand domain. {ECO:0000305}.
SimilarityContains 1 PI-PLC X-box domain. {ECO:0000255|PROSITE- ProRule:PRU00270}.
SimilarityContains 1 PI-PLC Y-box domain. {ECO:0000255|PROSITE- ProRule:PRU00271}.
Subcellular LocationCell membrane {ECO:0000250}; Peripheral membrane protein {ECO:0000250}.
Tissue SpecificityExpressed in stems, leaves, roots, flowers and siliques. Predominant in the vascular tissues of roots and leaves. {ECO:0000269|PubMed:7732004, ECO:0000269|Ref.7}.
