Predicted to enable C-C chemokine binding activity and C-C chemokine receptor activity. Predicted to be involved in several processes, including calcium-mediated signaling; cell chemotaxis; and positive regulation of cytosolic calcium ion concentration. Predicted to act upstream of or within G protein-coupled receptor signaling pathway. Predicted to be located in endosome and plasma membrane. Predicted to be integral component of membrane. Predicted to be active in external side of plasma membrane. Is expressed in several structures, including central nervous system; gut; immune system; male reproductive gland or organ; and sensory organ. Orthologous to human ACKR4 (atypical chemokine receptor 4). [provided by Alliance of Genome Resources, Apr 2022]
