Non-specific phospholipase C4

UniProtKB accession:  Q9SRQ7

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Non-specific phospholipase C (PLC) which assumes major PLC activity during inorganic phosphate starvation. Substrate preference is phosphatidylcholine (PC), but can also hydrolyze phosphatidylethanolamine (PE) with lower efficiency. Has no activity toward phosphatidic acid (PA). Plays an important role in the supply of both inorganic phosphate and diacylglycerol from membrane-localized phospholipids during phosphate deprivation. May be required for lipid-derived signaling molecules that positively modulate abscisic acid (ABA) response and promote plant tolerance to drought and salt stresses. May be involved in brassinolide-mediated signaling in root development.
