Snake venom phospholipase A2 homolog that lacks enzymatic activity (PubMed:25522251). Is able to suppress the acetylcholine (ACh)-evoked current mediated by alpha-7-similar nAChRs in L.stagnalis neurons (IC(50)=2.18 uM) (PubMed:25522251). This activity is only partially reversible and seems to be non-competitive (PubMed:25522251). Expressed by the venom gland. Belongs to the phospholipase A2 family. Group II subfamily. S49 sub-subfamily. This protein is not found in the crude venom. Does not bind calcium as one of the calcium-binding sites is lost (Asp->Ser in position 64, which corresponds to 'Ser-49' in the current nomenclature).
