Receptor for C-C type chemokine. Binds and responds to a variety of chemokines, including CCL11, CCL26, CCL7, CCL13, RANTES(CCL5) and CCL15. Subsequently transduces a signal by increasing the intracellular calcium ions level. In addition acts as a possible functional receptor for NARS1. Detected in skeletal muscle and in trace amounts in leukocytes. Deficient mice with induced pulmonary inflammation exhibit reduced trafficking of eosinophils from the blood into the lung parenchyma and increased numbers of intraepithelial mast cells in the trachea. Cholinergic stimulation resulted in airway hyperresponsiveness. Belongs to the G-protein coupled receptor 1 family.
