WebBackground: Recently, the expression of proteinase-activated receptor 2 (PAR2) has been shown to be essential for activin receptor-like kinase 5 (ALK5)/SMAD-mediated signaling and cell migration by transforming growth factor (TGF)-β1. However, it is not known whether activation of non-SMAD TGF-β signaling (e.g., RAS–RAF–MEK–extracellular signal … 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.
