[https://www.uniprot.org/uniprot/A1HA_LOXIN A1HA_LOXIN] Catalyzes the hydrolysis of sphingomyelin, lysophosphatidylcholine, and lyso-platelet activating factor but not that of phosphatidylcholine. Shows a high enzymatic activity. Induces dermonecrosis, blood vessel permeability and platelet aggregation (PubMed:9790962). Is directly toxic to kidney (PubMed:16005484) and liver (PubMed:18765244). Also induces hemolysis in a complement-dependent manner (PubMed:9790962) as well as in a complement-independent manner. The hemolysis provoked in a complement-independent manner is composed of several steps. The toxin binds to erythrocyte membranes, hydrolyzes membrane phospholipids (sphingomyelin and lysophosphatidylcholine) thus generating metabolism products that cause hemolysis, probably by provoking an increase of calcium inside cells. The calcium influx is due to the opening of L-type calcium channels, since L-type calcium channel blockers inhibit calcium influx (PubMed:21590705).<ref>PMID:16005484</ref> <ref>PMID:18760322</ref> <ref>PMID:18765244</ref> <ref>PMID:19455508</ref> <ref>PMID:21590705</ref> <ref>PMID:9790962</ref> | |||
