Predicted to enable cytokine activity; identical protein binding activity; and macrophage colony-stimulating factor receptor binding activity. Predicted to be involved in several processes, including interleukin-34-mediated signaling pathway; positive regulation of cell differentiation; and positive regulation of macromolecule metabolic process. Predicted to act upstream of or within positive regulation of MAP kinase activity and positive regulation of protein tyrosine kinase activity. Predicted to be active in extracellular space. Orthologous to human IL34 (interleukin 34). [provided by Alliance of Genome Resources, Apr 2022]
