Elicits platelet aggregation by the binding to the C-type lectin domain family 1 member B (CLEC1B/CLEC2). Binding leads to tyrosine phosphorylation in the cytoplasmic tail of CLEC1B, which promotes the binding of spleen tyrosine kinase (Syk), subsequent activation of PLC-gamma-2, and platelet activation and aggregation. Binding to GPIbalpha (GP1BA) and alpha-2/beta-1 (ITGA2/ITGB1) may also induce aggregation, but this is controversial. Snaclec rhodocytin subunit alpha Protein, Calloselasma rhodostoma, Recombinant (His) is expressed in yeast with N-6xHis tag. The predicted molecular weight is 17.8 kDa and the accession number is Q9I841.
