Predicted to enable C-C chemokine binding activity and C-C chemokine receptor activity. Predicted to be involved in several processes, including positive regulation of immune response; positive regulation of leukocyte chemotaxis; and regulation of cytokine production. Predicted to act upstream of or within chemotaxis and homeostasis of number of cells. Predicted to be located in cell surface; mitochondrion; and plasma membrane. Predicted to be active in external side of plasma membrane. Orthologous to human CCR7 (C-C motif chemokine receptor 7). [provided by Alliance of Genome Resources, Apr 2022]
