Description:Interleukin 34 (IL-34) was originally identified in humans, by large scale screening of secreted proteins; orthologs have also been found in chimpanzee, murine, rat and chicken. Human IL-34 is synthesized as a 242 amino acid (aa) precursor that contains a 20 aa signal sequence and a 222 aa mature chain. IL-34 is secreted as a homodimer and contains one potential N-glycosylation site. IL-34 increases proliferation of immune cells known as monocytes; it elicits its activity by binding the Colony Stimulating Factor 1 Receptor (CSF-1R). Expression of IL-34 is most abundant in the spleen and is expressed in many other tissues including the heart, brain, liver, kidney, thymus, intestine and lung. Human IL-34 contains a C-terminal 6x-polyhistidine (6xHis) tag.
