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 domain tail of CLEC1B, which promotes the binding of spleen tyrosine kinase (Syk), subsequent activation of PLCgamma2, and platelet activation and aggregation. Binding to GPIbalpha (GP1BA) and alpha2,beta-1 (ITGA2,ITGB1) may also induce aggregation, but this is controversial.
