G-protein coupled receptor 52 (GPR52)

Gs-coupled receptor triggered by antipsychotics reserpine leading to an increase in intracellular cAMP and its internalization (PubMed:24587241). May play a role in locomotor activity through modulation of dopamine, NMDA and ADORA2A-induced locomotor activity.

These behavioral changes are accompanied by modulation of the dopamine receptor signaling pathway in striatum (PubMed:24587241). Modulates HTT level through cAMP-dependent but PKA independent mechanics throught activation of RAB39B which translocates HTT to the endoplasmic reticulum, thus avoiding proteasome degradation (PubMed:25738228).
