Definition: A secreted phospholipase A2 subtype that contains a interfacial-binding region with specificity for PHOSPHATIDYLCHOLINE. This enzyme group may play a role in eliciting ARACHIDONIC ACID release from intact cellular membranes and from LOW DENSITY LIPOPROTEINS. Members of this group bind specifically to PHOSPHOLIPASE A2 RECEPTORS.
Other names sPLA2-X; sPLA(2)-X; Phospholipase A2, Group X; Group X Secretory Phospholipase A2; Group X Secretory Phospholipase A(2); GX sPLA(2); Phospholipases A2, Group X
