Receptor for chemoattractant adipokine chemerin/RARRES2 suggesting a role for this receptor in the regulation of inflammation and energy homesotasis (PubMed:24895415). 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 (PubMed:29799787). Internalizes in presence of its ligand, TAFA1 (PubMed:29799787). Internalizes efficiently in response to RARRES2 (By similarity). High expressed in white adipose tissue and skeletal muscle (PubMed:24895415). Expressed in hippocampus and cortex (PubMed:29799787). Deficient mice have normal body weight, adipose development, and tissue inflammation under physiologic conditions. However, when fed on a high-fat diet, Cmklr2 knockout mice develop heightened glucose intolerance, compared with WT, with no effect on body weight, percent body fat, or energy expenditure due to consumption of significantly less food. Moreover, mice lacking Cmklr2 exhibited reduced glucose-stimulated insulin levels and elevated glucose levels in a pyruvate tolerance test. Belongs to the chemokine-like receptor (CMKLR) family.
