Dimers of the Neuropeptide Y (NPY) Y2 Receptor Show Asymmetry in Agonist Affinity and Association with G Proteins

In conditions precluding activation of G proteins, the binding of agonists to dimers of the neuropeptide Y (NPY) Y2 receptor shows two components of similar size, but differing in affinity. The dimers of all NPY receptors are solubilized as ∼ 180-kDa complexes containing one G protein α β γ trimer....
