Template:ABSTRACT PUBMED 14521935

Function

[SLA_CRODU] Snake venom lectin that activates platelets by binding to the platelet collagen receptor glycoprotein VI (GP6) (PubMed:9153205). The indirect activation of integrin alpha-IIb/beta-3 (ITGA2B/ITGB3) also induced by the toxin is upstream the cytoskeletal translocation of GPIb, FcRgamma (FCER1G) and 14-3-3zeta (YWHAZ)(PubMed:16102113).[1] [2] [SLB_CRODU] Snake venom lectin that activates platelets by binding to the platelet collagen receptor glycoprotein VI (GP6) (PubMed:9153205). The indirect activation of integrin alpha-IIb/beta-3 (ITGA2B/ITGB3) also induced by the toxin is upstream the cytoskeletal translocation of GPIb, FcRgamma (FCER1G) and 14-3-3zeta (YWHAZ)(PubMed:16102113).[3] [4]
