General annotation (Comments)

Function	Pro-inflammatory cytokine. Involved in the innate immune response to bacterial pathogens. The expression of MIF at sites of inflammation suggests a role as mediator in regulating the function of macrophages in host defense. Counteracts the anti-inflammatory activity of glucocorticoids. Has phenylpyruvate tautomerase and dopachrome tautomerase activity (in vitro), but the physiological substrate is not known. It is not clear whether the tautomerase activity has any physiological relevance, and whether it is important for cytokine activity By similarity.
Catalytic activity	Keto-phenylpyruvate = enol-phenylpyruvate. L-dopachrome = 5,6-dihydroxyindole-2-carboxylate.
Subunit structure	Homotrimer. Interacts with BNIPL By similarity. Interacts with the CD74 extracellular domain. Interacts with COPS5 and with the CXCR2 extracellular domain By similarity.
Subcellular location	Secreted By similarity. Cytoplasm By similarity. Note: Does not have a cleavable signal sequence and is secreted via a specialized, non-classical pathway. Secreted by macrophages upon stimulation by bacterial lipopolysaccharide (LPS), or by M.tuberculosis antigens By similarity.
Sequence similarities	Belongs to the MIF family.
