Predicted to enable CCR chemokine receptor binding activity and chemokine activity. Predicted to be involved in several processes, including cellular response to cytokine stimulus; leukocyte chemotaxis; and positive regulation of ERK1 and ERK2 cascade. Predicted to act upstream of or within chemotaxis. Located in extracellular space. Is expressed in inguinal lymph node; thymus; and thymus primordium. Orthologous to human CCL22 (C-C motif chemokine ligand 22). [provided by Alliance of Genome Resources, Apr 2022]
