CC -!- FUNCTION: Pro-inflammatory cytokine involved in the innate immune
CC response to bacterial pathogens. The expression of MIF at sites of
CC inflammation suggests a role as mediator in regulating the function of
CC macrophages in host defense. Counteracts the anti-inflammatory activity
CC of glucocorticoids. Has phenylpyruvate tautomerase and dopachrome
CC tautomerase activity (in vitro), but the physiological substrate is not
CC known. It is not clear whether the tautomerase activity has any
CC physiological relevance, and whether it is important for cytokine
CC activity. {ECO:0000250|UniProtKB:P14174}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=3-phenylpyruvate = enol-phenylpyruvate; Xref=Rhea:RHEA:17097,
CC ChEBI:CHEBI:16815, ChEBI:CHEBI:18005; EC=5.3.2.1;
CC Evidence={ECO:0000250|UniProtKB:P14174};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-dopachrome = 5,6-dihydroxyindole-2-carboxylate;
CC Xref=Rhea:RHEA:13041, ChEBI:CHEBI:16875, ChEBI:CHEBI:57509;
CC EC=5.3.3.12; Evidence={ECO:0000250|UniProtKB:P14174};
CC -!- SUBUNIT: Homotrimer (By similarity). Interacts with CXCR2 extracellular
CC domain (By similarity). Interacts with the CD74 extracellular domain,
CC USO1, COPS5 and BNIPL (By similarity). {ECO:0000250|UniProtKB:P14174,
CC ECO:0000250|UniProtKB:P34884}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:P14174}.
CC Cytoplasm {ECO:0000250|UniProtKB:P14174}. Note=Does not have a
CC cleavable signal sequence and is secreted via a specialized, non-
CC classical pathway. Secreted by macrophages upon stimulation by
CC bacterial lipopolysaccharide (LPS), or by M.tuberculosis antigens.
CC {ECO:0000250|UniProtKB:P14174}.
CC -!- SIMILARITY: Belongs to the MIF family. {ECO:0000305}.
