Protein

Group 10 secretory phospholipase A2

Gene

Pla2g10

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein 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.

Catalytic activityi

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