UniProt functional annotation for O93426

UniProt code: O93426.

Organism: Crotalus durissus terrificus (South American rattlesnake).
Taxonomy: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Lepidosauria; Squamata; Bifurcata; Unidentata; Episquamata; Toxicofera; Serpentes; Colubroidea; Viperidae; Crotalinae; Crotalus.
 
Function: 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). {ECO:0000269|PubMed:16102113, ECO:0000269|PubMed:9153205}.
 
Subunit: Tetramer of heterodimers of alpha and beta subunits (alphabeta)(4); disulfide-linked.
Subcellular location: Secreted.
Tissue specificity: Expressed by the venom gland.
Miscellaneous: Does not act by binding to GPIb. {ECO:0000305|PubMed:9153205}.
Similarity: Belongs to the snaclec family. {ECO:0000305}.
