Protein

Group 10 secretory phospholipase A2

Gene

Pla2g10

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: -Experimental evidence at transcript leveli

Functioni

PA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides. Has a powerful potency for releasing arachidonic acid from cell membrane phospholipids (By similarity).By similarity

Catalytic activityi

Phosphatidylcholine + H2O = 1-acylglycerophosphocholine + a carboxylate.PROSITE-ProRule annotation

Cofactori

Ca2+By similarityNote: Binds 1 Ca2+ ion per subunit.By similarity
