Cellular membranes are composed of proteins and glyco- and phospholipids and play an indispensible role in maintaining cellular integrity and homeostasis, by physically restricting biochemical processes within cells and providing protection. Membrane proteins perform many essential functions, which include operating as transporters, adhesion-anchors, receptors, and enzymes. Recent advancements in proteomic mass spectrometry have resulted in substantial progress towards the determination of the plasma membrane (PM) proteome, resolution of membrane protein topology, establishment of numerous receptor protein complexes, identification of ligand-receptor pairs, and the elucidation of signaling networks originating at the PM. Here, we discuss the recent accelerated success of discovery-based proteomic pipelines for the establishment of a complete membrane proteome.
细胞膜由蛋白质、糖脂和磷脂组成,通过物理限制细胞内的生化过程并提供保护,在维持细胞完整性和动态平衡方面发挥着不可或缺的作用。膜蛋白具有许多重要的功能,包括作为转运蛋白、黏附锚、受体和酶发挥作用。蛋白质组学质谱分析技术的最新进展,使得人们在确定质膜(PM)蛋白质组、解析膜蛋白拓扑结构、建立众多受体蛋白复合物、鉴定配体-受体对以及阐明源自 PM 的信号网络方面取得了实质性的进展。在这里,我们讨论了基于发现的蛋白质组学管道最近取得的加速成功,以建立完整的膜蛋白质组。
