Summary
Description
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
3-phenylpyruvate = enol-phenylpyruvate
L-dopachrome = 5,6-dihydroxyindole-2-carboxylate
Biophysicochemical Properties
249 uM for phenylpyruvate
168 uM for p-hydroxyphenylpyruvate
Subunit
Homotrimer.
Homotrimer. Interacts with BNIPL (By similarity). Interacts with the CD74 extracellular domain. Interacts with COPS5 and with the CXCR2 extracellular domain (By similarity).
Homotrimer. Interacts with CXCR2 extracellular domain (By similarity). Interacts with the CD74 extracellular domain, COPS5 and BNIPL.
Miscellaneous
Serum levels of MIF are elevated in patients with severe sepsis or septic shock. High levels of MIF are correlated with low survival. Drugs that inhibit tautomerase activity protect against death due to sepsis.
Similarity
Belongs to the MIF family.
