两极性聚合物(APols)是一种短的两亲性聚合物,可以在膜蛋白(MPs)的跨膜表面替代洗涤剂,从而使其在无洗涤剂的水溶液中保持可溶性。通常,pol捕获的MPs比洗涤剂溶解的同类更稳定。apol已被证明对生成MPs是有用的,最显著的是通过在SDS或尿素中溶解MP包涵体后帮助它们从变性状态折叠。它们有助于在水溶液中处理脆弱的MPs,用于蛋白质组学、结构和功能研究以及治疗学。由于apol可以被化学标记或功能化,并且它们与MPs形成非常稳定的配合物,它们也可以用于间接功能化MPs,这开辟了许多新的应用。在简要回顾APol和MP/APol复合物的性质之后,提供了这些不同领域的最新进展。
Amphipols (APols) are short amphipathic polymers that can substitute for detergents at the transmembrane surface of membrane proteins (MPs) and, thereby, keep them soluble in detergent-free aqueous solutions. APol-trapped MPs are, as a rule, more stable biochemically than their detergent-solubilized counterparts. APols have proven useful to produce MPs, most noticeably by assisting their folding from the denatured state obtained after solubilizing MP inclusion bodies in either SDS or urea. They facilitate the handling in aqueous solution of fragile MPs for the purpose of proteomics, structural and functional studies, and therapeutics. Because APols can be chemically labeled or functionalized, and they form very stable complexes with MPs, they can also be used to functionalize those indirectly, which opens onto many novel applications. Following a brief recall of the properties of APols and MP/APol complexes, an update is provided of recent progress in these various fields.
