RT   "Ophioluxin, a convulxin-like C-type lectin from Ophiophagus hannah (King
RT   cobra) is a powerful platelet activator via glycoprotein VI.";
RL   J. Biol. Chem. 277:35124-35132(2002).
CC   -!- FUNCTION: Binds to the platelet and collagen receptor glycoprotein VI
CC       (GP6) and activates platelet aggregation.

CC   -!- SUBUNIT: Heterodimer of subunits alpha and beta; disulfide-linked.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom gland.
CC   -!- PTM: May be glycosylated.
CC   -!- MISCELLANEOUS: Does not agglutinate fixed platelets.
CC       {ECO:0000305|PubMed:12130642}.
CC   -!- SIMILARITY: Belongs to the snaclec family. {ECO:0000305}.
