Disease

[MIF_HUMAN] Genetic variations in MIF are associated with susceptibility to rheumatoid arthritis systemic juvenile (RASJ) [MIM:604302]. An inflammatory articular disorder with systemic-onset beginning before the age of 16. It represents a subgroup of juvenile arthritis associated with severe extraarticular features and occasionally fatal complications. During active phases of the disorder, patients display a typical daily spiking fever, an evanescent macular rash, lymphadenopathy, hepatosplenomegaly, serositis, myalgia and arthritis.

Function

[MIF_HUMAN] 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.^[1] ^[2]

Publication Abstract from PubMed

Regulation of cellular processes by dietary nutrients is known to affect the likelihood of cancer development. One class of cancer-preventive nutrients, isothiocyanates (ITCs), derived from the consumption of cruciferous vegetables, is known to have various effects on cellular biochemistry. One target of ITCs is macrophage migration inhibitory factor (MIF), a widely expressed protein with known inflammatory, pro-tumorigenic, pro-angiogenic, and anti-apoptotic properties. MIF is covalently inhibited by a variety of ITCs, which in part may explain how they exert their cancer-preventive effects. We report the crystallographic structures of human MIF bound to phenethylisothiocyanate and to l-sulforaphane (dietary isothiocyanates derived from watercress and broccoli, respectively) and correlate structural features of these two isothiocyanates with their second-order rate constants for MIF inactivation. We also characterize changes in the MIF structure using nuclear magnetic resonance heteronuclear single-quantum coherence spectra of these complexes and observe many changes at the subunit interface. While a number of chemical shifts do not change, many of those that change do not have features similar in magnitude or direction for the two isothiocyanates. The difference in the binding modes of these two ITCs provides a means of using structure-activity relationships to reveal insights into MIF biological interactions. The results of this study provide a framework for the development of therapeutics that target MIF.
