Trace amine-associated receptor 8 is a protein that in humans is encoded by the TAAR8 gene.[5][6][7] In humans, TAAR8 is the only trace amine-associated receptor that is known to be Gi/o-coupled.[8]

In humans, molecular modelling and docking experiments have shown that putrescine fits into the binding pocket of the human TAAR6 and TAAR8 receptors.[9]

G protein-coupled receptors (GPCRs, or GPRs) contain 7 transmembrane domains and transduce extracellular signals through heterotrimeric G proteins.[supplied by OMIM][7]
