Enables chemokine activity. Involved in several processes, including leukocyte chemotaxis; positive regulation of tumor necrosis factor production; and positive regulation of vascular permeability. Predicted to be active in extracellular space. Biomarker of anti-basement membrane glomerulonephritis; obesity; and status epilepticus. Human ortholog(s) of this gene implicated in acquired immunodeficiency syndrome and human immunodeficiency virus infectious disease. Orthologous to several human genes including CCL4L2 (C-C motif chemokine ligand 4 like 2). [provided by Alliance of Genome Resources, Apr 2022]
