Protein

Macrophage migration inhibitory factor

Gene

MIF

Organism
Meriones unguiculatus (Mongolian jird) (Mongolian gerbil)
Status
Reviewed - Annotation score: 4 out of 5- Protein inferred from homologyi

Functioni

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).By similarity

Catalytic activityi

Keto-phenylpyruvate = enol-phenylpyruvate.
L-dopachrome = 5,6-dihydroxyindole-2-carboxylate.
