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 and chemotaxis. Predicted to be located in early endosome and membrane. Predicted to be active in external side of plasma membrane. Is expressed in thymus. Orthologous to human CCR9 (C-C motif chemokine receptor 9).
