Increased phospholipase A 2 has also been associated with neuropsychiatric disorders such as schizophrenia and pervasive developmental disorders (such as autism), though the mechanisms involved are not known. Isozymes. Human phospholipase A 2 isozymes include: Group I: PLA2G1B; Group II: … See more The enzyme phospholipase A2 (EC 3.1.1.4, PLA2, systematic name phosphatidylcholine 2-acylhydrolase) catalyse the cleavage of fatty acids in position 2 of phospholipids, hydrolyzing the bond between the … See more Phospholipases A2 include several unrelated protein families with common enzymatic activity. Two most notable families are secreted and cytosolic phospholipases A2. … See more PLA2 action can release histamine from rat peritoneal mast cells. It also causes histamine release in human basophils. See more In normal brain cells, PLA2 regulation accounts for a balance between arachidonic acid's conversion into proinflammatory mediators and its reincorporation into … See more The suggested catalytic mechanism of pancreatic sPLA2 is initiated by a His-48/Asp-99/calcium complex within the active site. The calcium ion polarizes the sn-2 carbonyl oxygen while also coordinating with a catalytic water molecule, w5. His … See more Due to the importance of PLA2 in inflammatory responses, regulation of the enzyme is essential. cPLA2 is regulated by phosphorylation and calcium concentrations. cPLA2 is phosphorylated by a MAPK at Serine-505. When phosphorylation is … See more Human phospholipase A2 isozymes include: • Group I: PLA2G1B • Group II: PLA2G2A, PLA2G2C, PLA2G2D, PLA2G2E, PLA2G2F • Group III: PLA2G3 See more Web"Cytoplasmic phospholipase A2 levels correlate with apoptosis in human colon tumorigenesis".
