== Function == | |||
'''Macrophage inhibitory factor''' or '''Macrophage migration inhibitory factor''' (MIF) is an inflammatory cytokine. '''MIF2''' or '''D-dopachrome tautomerase''' or '''D-dopachrome decarboxylase''' is a pro-inflammatory cytokine which regulates the innate and adaptive immune response<ref>PMID:22507380</ref>. MIF is released to the blood stream upon stimulation of white blood cells by bacterial antigens<ref>PMID:11032394</ref>. | |||
== Relevance == | |||
MIF plays a role in various solid and hematologic tumors<ref>PMID:19326434</ref>. MIF is overexpressed in various tumors and is suggested to be the molecular link between chronic inflammation and cancer. MIF has a role in skin inflammation, immune response, disease, tumorigenesis and wound healing<ref>PMID:15659324</ref>. MIF has a role in Alzheimer disease and its inhibition may prevent the disease onset<ref>PMID:20200619</ref>. | |||
== Structural highlights == | |||
MIF contains two different catalytic sites. A phenylpyruvate tautomerase site is located in the N terminal. A <scene name='55/551208/Cv/5'>disulfide reductase site is located in the tetrapeptide Cys-Ala-Leu-Cys in position 57-60</scene>. The <scene name='55/551208/Cv/6'>inhibitor binds to the pro-inflammatory tautomerase site</scene><ref>PMID:17526494</ref>. Water molecules shown as red spheres. | |||
