Seven transmembrane (7-TM) proteins function as monomers but can also dimerize (or oligomerize). Although most 7-TM proteins are metabotropic receptors (A, C–E) there are a few examples of ionotropic 7-TM receptors (B, E).(A) Most common for a 7-TM protein is to function as G protein-coupled receptor (GPCR).
