Macrophage migration inhibitory factor (P14174)

Uniprot ID P14174
Protein Name Macrophage migration inhibitory factor
Gene Name MIF
Species Homo sapiens (Human)
Signal peptide(a) N Secretome P(b) 0.925
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. .
