Abstract:
The c-type lectin-like receptor 2 (CLEC-2) was first identified from a bio-informatic screen for c-type lectin-like receptors. However, neither its function nor its ligand(s) had been elucidated for several years. In 2006, we reported that the receptor is expressed on the surface of platelets and serves as a receptor for the snake venom rhodocytin, which potently stimulates platelet aggregation. Since then CLEC-2 has been intensively investigated, and its endogenous/exogenous ligands and several physiological/pathological roles have been clarified. In this article and its accompanying poster, we outline the structure, distribution, signal transduction mechanism and functions of CLEC-2.

Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
Structure and Function of Platelets
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000 platelets, with...
