背景(Background)
Furin也被稱為配對堿性氨基酸切割酶(PACE),是一種屬于枯草桿菌蛋白酶樣前蛋白轉(zhuǎn)化酶家族的酶。該家族的成員是前蛋白轉(zhuǎn)化酶,將潛在的前體蛋白轉(zhuǎn)化為其生物活性產(chǎn)物。Furin在高爾基體中富集,其功能是將其他蛋白質(zhì)切割成成熟/活性形式。弗林蛋白酶在T細胞中的表達是維持外周免疫耐受所必需的。Furin切割位于基本氨基酸靶序列下游的蛋白質(zhì)(通常為Arg-X-(Arg/Lys)-Arg')。PACE是一種鈣依賴性絲氨酸內(nèi)蛋白酶,可以在其配對的堿性氨基酸加工位點有效切割前體蛋白。除了加工細胞前體蛋白外,弗林蛋白酶還被許多病原體利用。例如,HIV、流感和登革熱病毒的包膜蛋白必須被弗林蛋白酶或弗林蛋白酶樣蛋白酶切割才能完全發(fā)揮作用。PACE也在腫瘤進展中發(fā)揮作用。
