概述
Macrophage migration inhibitory factor(MIF or MMIF),also named as glycosylation-inhibiting factor(GIF),L-dopachrome isomerase,or phenylpyruvate tautomerase,is a protein encoded by the MIF gene.It is released from white blood cells by bacterial antigen stimulation to trigger an acute immune response,or by glucocorticoids to counter-act the inhibitory effects of glucocorticoids on immune system.MIF is a homotrimer of which each subunit contains 115 amino acids.As mentioned above,MIF is involved in the innate immune response to bacterial pathogens and counter-acts the anti-inflammatory activity of glucocorticoids.Furthermore,it also plays a role as mediator in regulating the function of macrophages in host defense and has phenylpyruvate tautomerase and dopachrome tautomerase activity in vitro.Rat MIF is 99%,90%,89%,and 89%a.a.identical to human,murine,porcine and bovine,respectively.
