Webtransmembrane helices that are connected by intracellular and extracellular loops, and are arranged around a central pocket [14]. Extracellular loop II (ECLII) is located between transmembrane helices 4 and 5. In PAR 1, ECLII is a binding site for the tethered ligand [15] but very little is known about the homologous region on PAR4. WebProteolytic cleavage leads to the activation of the receptor. F2R is a G-protein coupled receptor family member. Alternative splicing results in multiple transcript variants.
