Predicted to enable CCR1 chemokine receptor binding activity; chemoattractant 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. Predicted to be located in extracellular region. Predicted to be active in extracellular space. Is expressed in several structures, including brain and retina nuclear layer. Orthologous to several human genes including CCL23 (C-C motif chemokine ligand 23).
