9.A.14.13.25
G-protein coupled receptor 139, GPR139, GPRG1 or PGR3, of 353 aas and 7 TMSs.  It is an orphan receptor that seems to act through a G(q/11)-mediated pathway.  GPR139 and the dopamine D2 receptor co-express in the same cells of the brain and may functionally interact (Wang et al. 2019). Loss of GPR139 enhanced effects of morphine in mice but reduced withdrawal effects (Wang et al. 2019). It is a regulator of opioid receptors (Lindsay and Scherrer 2019).
