Glycoprotein VI (platelet) also known as GPVI is a glycoprotein receptor for collagen which is expressed in platelets. In humans, glycoprotein VI is encoded by the GPVI gene.
Proteins are made of amino acids, such as glycine, proline, arginine, hydroxyproline, which are amino acids that exist in collagen in varying proportions, depending upon the source. As the largest protein in the body, collagen is a chain of over 1500 amino acids.
