朊粒蛋白

(重定向自PRNP)
朊粒蛋白[6][7](prion protein,PrP[8][9])音译普里昂蛋白,又名朊毒体蛋白[10],是在人和动物体内普遍存在并具有一定生理功能的蛋白[11],但其异常折叠可能在人或动物中引起致死性神经退行性疾病。缩写 PrP 的 Pr 代表朊粒,P 代表蛋白;由於 PrP 一般是機體正常的大分子,稱朊“毒”体蛋白可能造成誤解。
朊粒蛋白在人体中由 PRNP 基因编码,该基因也称为CD230(分化群230)[12][13][14][15]。该蛋白表达主要存在于神经系统,但也广泛存在于全身其他多种组织中[16][17][18]。
作为多种神经退行性疾病致病源的朊粒蛋白,原本是机体内一种正常表达蛋白,其可存在多种异构体形式,如常见正常的 PrPC(cellular prion protein) 形式,具抗蛋白酶特性而致病的 PrPRes 形式,以及一种位于线粒体中的异构体[19]。PrPRes 的常见例子如:PrPSc,是羊瘙痒病相关蛋白。
