概述

Migration Inhibitory Factor(MIF)is a secreted protein without a cleavable signal sequence and is secreted via a specialized,non-classical pathway.It is secreted by macrophages upon stimulation by bacterial lipopolysaccharide(LPS),or by M.tuberculosis antigens.MIF consists of two α-helices and six β-strands,four of which form a β-sheet.The two remaining β-strands interact with other MIF molecules,creating a trimer.Structure-function studies suggest MIF is bifunctional with segregated topology.The N- and C-termini mediate enzyme activity(in theory).Phenylpyruvate tautomerase activity(enol-to-keto)has been demonstrated and is dependent upon Pro at position 1.Amino acids 50-65(a.a.)have also been suggested to contain thiol-protein oxidoreductase activity.MIF has proinflammatory cytokine activity centered around 49 - 65(a.a.).On fibroblasts,MIF induces,IL-1,IL-8 and MMP expression;on macrophages,MIF stimulates NO production and TNF-α release folllowing IFN-γ activation.MIF apparently acts through CD74 and CD44,likely in some form of trimeric interaction.Human MIF is active on mouse cells.Human MIF is 90%,94%,95%,and 90%a.a.identical to mouse,bovine,porcine and rat MIF,respectively.
