CLEC1B

A gene on chromosome 12p13.2 that encodes a C-type lectin domain protein which acts as a receptor for the platelet-aggregating snake venom protein rhodocytin. Rhodocytin binding triggers tyrosine phosphorylation, spleen tyrosine kinase (Syk) binding, downstream tyrosine phosphorylation and activation of PLC-gamma-2. CLEC1B acts as an attachment factor for HIV-1, facilitating its capture by platelets. It is expressed in the liver, myeloid cells and on platelets.

In 2000, another set of investigators came across a protein on the surface of platelets and dubbed it C-type lectin-like receptor 2, or CLEC-2.
