胞内无序蛋白(IDP)是细胞信号机制的重要组成部分,允许相同的多肽进行不同的相互作用,产生不同的结果。IDP受到组合的翻译后修饰和选择性剪接,增加了调控网络的复杂性,并提供了组织特异性信号传导的机制。IDP参与信号复合物的组装和无膜细胞核和细胞质细胞器的动态自组装。实验、计算和生物信息学分析结合联合收割机来识别和表征蛋白质的无序区域,从而更好地了解它们在生物过程中的广泛作用。
Intrinsically disordered proteins (IDPs) are important components of the cellular signaling machinery, allowing the same polypeptide to undertake different interactions with different consequences. IDPs are subject to combinatorial post-translational modifications and alternative splicing, adding complexity to regulatory networks and providing a mechanism for tissue-specific signaling. IDPs participate in assembly of signaling complexes and in the dynamic self-assembly of membrane-less nuclear and cytoplasmic organelles. Experimental, computational and bioinformatic analysis combine to identify and characterize disordered regions of proteins, leading to a greater appreciation of their widespread role in biological processes.
