Anti-GPR1

function:Orphan receptor. Probable opioid receptor. Can act as a co-receptor for HIV-1.,similarity:Belongs to the G-protein coupled receptor 1 family.,tissue specificity:Expressed in hippocampus., Protein function: Receptor for chemoattractant adipokine chemerin/RARRES2 suggesting a role for this receptor in the regulation of inflammation and energy homesotasis (PubMed:18165312, PubMed:27716822). Signals mainly via beta-arrestin pathway. Binding of RARRES2 activates weakly G proteins, calcium mobilization and MAPK1/MAPK3 (ERK1/2) phosphorylation too (PubMed:27716822). Acts also as a receptor for TAFA1, mediates its effects on neuronal stem-cell proliferation and differentiation via the activation of ROCK/ERK and ROCK/STAT3 signaling pathway. [The UniProt Consortium] Recommended dilutions: Immunofluorescence: 1/200 - 1/1000. ELISA: 1/5000. Not yet tested in other applications.. Cellular localization: Cell membrane , Multi-pass membrane protein . Internalizes in presence of its ligand, TAFA1 (By similarity). Internalizes efficiently in response to RARRES2 (PubMed:27716822). .
