== Function == | |||
[[Phospholipase A2]] (PLA2) is an enzyme which releases fatty acids from glycerol. It is found in mammals and in snake venoms. PLA2 releases arachidonic acid from membranes causing inflammation and pain. PLA2 | [[Phospholipase A2]] (PLA2) is an enzyme which releases fatty acids from glycerol. It is found in mammals and in snake venoms<ref>PMID:8175726</ref>. PLA2 releases arachidonic acid from membranes causing inflammation and pain. The PLA2 contains many isozymes which are ordered by groups and named accordingly, ie., group I is PLA2G1.<br /> | ||
*'''PLA2 group II''' is induced in inflammation and present in atherosclerotic lesions<ref>PMID:10323782</ref>. <br /> | |||
*'''PLA2 group V''' is active in leukocytes recruitment<ref>PMID:20232296</ref>. <br /> | |||
*'''PLA2 group X''' regulates cysteinyl leukotriene synthesis<ref>PMID:26139511</ref>. <br /> | |||
*'''PLA2 group XV''' is located in the endocytic system and may be involved in CD1d function<ref>PMID:23943550</ref>. <br /> | |||
*'''Bothropstoxin (BTX)''' is PLA2 from the snake ''Bothrops jararacussu''.<br /> | |||
*'''Piratoxin (PTX)''' is PLA2 from the snake ''Bothrops piraña''.<br /> | |||
*'''Viperotoxin (VTX)''' is a heterodimer of a very homologous PLA2 called '''RV-4/RV-7'''.<br /> | |||
*'''Cystolic PLA2 (cPLA2)''' is intracellular. It is larger than the secreted PLA2 and contains the targeting C2 domain. <br /> | |||
*'''Pro-phosphlipase (PPLA2)''' is a pancreatic PLA2 whose 7-mer N-terminal peptide is cleaved off to produce the active PLA2.<br /> | |||
