Research Abstract

Functional G-protein coupled receptors are believed to be functional when dimerized. Still, in the receptor dimer, each subunit(one receptor molecule) binds to one agonist, respectively. When coexpressed with Snapin, which intereacts with alpha-1A receptors, Sanpin also dimerizes, and each Snapin can bind to the receptor. Thus, alpha-1A receptor can also form dimmer. Interestingly, the receptor dimer with Snapin can bin only to one agonist, suggesting that the functional dimmer when coexisted with Snapin may form a different structure from the dimmer without Snapin.
