Receptor for chemoattractant adipokine chemerin/RARRES2 suggesting a role for this receptor in the regulation of inflammation and energy homesotasis (By similarity). Signals mainly via beta-arrestin pathway. Binding of RARRES2 activates weakly G proteins, calcium mobilization and MAPK1/MAPK3 (ERK1/2) phosphorylation too. 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 (By similarity). Internalizes in presence of its ligand, TAFA1 (By similarity). Internalizes efficiently in response to RARRES2 (By similarity). Belongs to the chemokine-like receptor (CMKLR) family.
