Predicted to enable CCR7 chemokine receptor binding activity and chemokine activity. Predicted to be involved in several processes, including leukocyte chemotaxis; positive regulation of intracellular signal transduction; and regulation of leukocyte migration. Predicted to act upstream of or within induction of positive chemotaxis; lymph node development; and positive regulation of T cell migration. Predicted to be active in extracellular space. Orthologous to human CCL21 (C-C motif chemokine ligand 21). [provided by Alliance of Genome Resources, Apr 2022]
