Target type: molecularfunction
Catalysis of the reaction: a 1,2-diacyl-sn-glycero-3-phosphocholine + H2O = a 1,2-diacyl-sn-glycerol + H+ + phosphocholine. [GOC:mah, RHEA:10604]
Phosphatidylcholine phospholipase C (PC-PLC) activity is a crucial enzymatic function involved in the hydrolysis of phosphatidylcholine (PC), a major phospholipid component of cell membranes. This hydrolysis reaction releases two products: diacylglycerol (DAG) and phosphatidylinositol 4,5-bisphosphate (PIP2). DAG is a signaling molecule that activates protein kinase C (PKC), which in turn regulates a wide range of cellular processes, including cell growth, differentiation, and apoptosis. PIP2 is also a signaling molecule that is involved in a variety of cellular processes, including calcium signaling, actin cytoskeleton regulation, and vesicle trafficking. PC-PLC activity is tightly regulated by a variety of factors, including calcium ions, membrane lipids, and protein-protein interactions. This regulation ensures that PC-PLC activity is appropriately activated in response to specific cellular stimuli and contributes to the fine-tuning of downstream signaling pathways.'

| chlorpromazine | chlorpromazine : A substituted phenothiazine in which the ring nitrogen at position 10 is attached to C-3 of an N,N-dimethylpropanamine moiety. Chlorpromazine: The prototypical phenothiazine antipsychotic drug. Like the other drugs in this class chlorpromazine's antipsychotic actions are thought to be due to long-term adaptation by the brain to blocking DOPAMINE RECEPTORS. Chlorpromazine has several other actions and therapeutic uses, including as an antiemetic and in the treatment of intractable hiccup. | organochlorine compound; phenothiazines; tertiary amine | anticoronaviral agent; antiemetic; dopaminergic antagonist; EC 3.4.21.26 (prolyl oligopeptidase) inhibitor; phenothiazine antipsychotic drug |
| fendiline | Fendiline: Coronary vasodilator; inhibits calcium function in muscle cells in excitation-contraction coupling; proposed as antiarrhythmic and antianginal agents. | diarylmethane | |
| imipramine | imipramine : A dibenzoazepine that is 5H-dibenzo[b,f]azepine substituted by a 3-(dimethylamino)propyl group at the nitrogen atom. Imipramine: The prototypical tricyclic antidepressant. It has been used in major depression, dysthymia, bipolar depression, attention-deficit disorders, agoraphobia, and panic disorders. It has less sedative effect than some other members of this therapeutic group. | dibenzoazepine | adrenergic uptake inhibitor; antidepressant; EC 3.4.21.26 (prolyl oligopeptidase) inhibitor |
