半胱氨酸(Cys)蛋白质组是基因组和蛋白质组之间的适应性界面的主要组成部分。Cys的巯基部分经历一系列生物修饰,使得能够进行结构和反应性的生物转换。这些生物修饰包括亚磺酰化和二硫化物形成、形成更高的氧化态、S-亚硝基化、过硫化、金属化和其他修饰。现在,对这些系统及其区室化的广泛了解为开发Cys蛋白质组调节的先进综合模型提供了基础。特别是,氧化还原信号通路和传感网络的详细了解变得可用于区分网络结构。这项研究的重点是需要半胱氨酸修饰的图谱开发系统生物学模型。这样的图谱将是特别有用的综合研究连接的半胱氨酸蛋白质组成像和其他组学平台,提供了一个基础,为改善氧化还原为基础的治疗。因此,一个框架正在出现,将半胱氨酸蛋白质组作为定量蛋白质组的补充,在组学连续体中连接基因组和蛋白质组。
The cysteine (Cys) proteome is a major component of the adaptive interface between the genome and the exposome. The thiol moiety of Cys undergoes a range of biologic modifications enabling biological switching of structure and reactivity. These biological modifications include sulfenylation and disulfide formation, formation of higher oxidation states, S-nitrosylation, persulfidation, metallation, and other modifications. Extensive knowledge about these systems and their compartmentalization now provides a foundation to develop advanced integrative models of Cys proteome regulation. In particular, detailed understanding of redox signaling pathways and sensing networks is becoming available to discriminate network structures. This research focuses attention on the need for atlases of Cys modifications to develop systems biology models. Such atlases will be especially useful for integrative studies linking the Cys proteome to imaging and other omics platforms, providing a basis for improved redox-based therapeutics. Thus, a framework is emerging to place the Cys proteome as a complement to the quantitative proteome in the omics continuum connecting the genome to the exposome.
