哺乳动物组织通过活性氧(ROS)对蛋白质半胱氨酸残基的可逆修饰来调节特殊的生理机能。ROS调节了无数的生物过程,但在体内驱动组织特异性生理的ROS修饰的蛋白质靶点在很大程度上是未知的。在这里,我们开发了oximmouse,一个全面和定量的小鼠半胱氨酸氧化还原蛋白质组在体内的映射。我们使用oximmouse建立了几种生理氧化还原信号的范式。我们定义并验证了每个组织中具有组织选择性和组织特异性生物学基础的半胱氨酸氧化还原网络。我们描述了一种通过静电门控编码半胱氨酸氧化还原敏感性的共同机制。此外,我们全面鉴定了氧化还原修饰的疾病网络在老年小鼠中重塑,为氧化还原失调和组织衰老之间长期存在的联系建立了系统的分子基础。我们提供oximmouse纲要作为理解生理和衰老中氧化还原调节机制的框架。
Mammalian tissues engage in specialized physiology that is regulated through reversible modification of protein cysteine residues by reactive oxygen species (ROS). ROS regulate a myriad of biological processes, but the protein targets of ROS modification that drive tissue-specific physiology in vivo are largely unknown. Here we develop Oximouse, a comprehensive and quantitative mapping of the mouse cysteine redox proteome in vivo. We use Oximouse to establish several paradigms of physiological redox signaling. We define and validate cysteine redox networks within each tissue that are tissue-selective and underlie tissue-specific biology. We describe a common mechanism for encoding cysteine redox sensitivity by electrostatic gating. Moreover, we comprehensively identify redox-modified disease networks that remodel in aged mice, establishing a systemic molecular basis for the longstanding proposed links between redox dysregulation and tissue aging. We provide the Oximouse compendium as a framework for understanding mechanisms of redox regulation in physiology and aging.
