产品介绍
在真核生物细胞中,许多具有生物活性的多肽和蛋白是在其分泌过程中由前体蛋白经内切蛋白酶切割后激活形成的.弗林蛋白酶(Furin)就是这个内切蛋白酶家族重要成员之一,它可以识别剪切多种蛋白质,如生长医子、血清蛋白、基质金属蛋白酶、受体、病毒囊膜蛋白和细菌外毒素等.近年来Furin得到了迅速而广泛的研究,本文简介了它的表达与加工运输、生物学功能、与病毒侵染的关系,以及它的抑制剂.
背景资料
Furin is a calcium-dependent serine endoprotease that belongs to the subtilisin-like proprotein convertase family. The members of this family process latent precursor proteins into their biologically active products. Furin cleaves at paired basic amino acid processing sites within proparathyroid hormone, transforming growth factor β 1 precursor, proalbumin, pro-β-secretase, membrane type-1 matrix metalloproteinase, β subunit of pro-nerve growth factor and von Willebrand factor. Furin can directly cleave proMMP-2 within the ttrans-Golgi network leading to an inactive form of matrix metalloproteinase-2 (MMP-2). Furin is synthesized as an inactive zymogen that may minimize the occurrence of premature enzymatic activity that would lead to alternative protein activation or degradation. The inhibitory mechanism is based on the presence of an inactivating prosegment at the NH2 terminal of the Furin. After initial autocatalytic cleavage, the prosegment remains tightly associated until it reaches the trans-Golgi network where the dissociation of the prosegment and activation of furin occurs.
