Recent studies have implicated inositol phosphates, a highly charged family of lipid-derived metabolites, in a slue of cellular processes. However, it is their involvement in nuclear events that has attracted much attention. Several IP molecules have been linked to gene regulatory factors, chromatin-remodeling complexes, mRNA export, and DNA repair machinery, yet in many instances direct mechanistic roles remain elusive. The purpose of this review is to cover the latest data gathered regarding only the nuclear roles of the various inositol phosphates while simultaneously providing a step-by-step tour of IP synthesis in eukaryotes.
最近的研究表明,肌醇磷酸盐是一类高度带电的脂质衍生代谢物,参与了许多细胞过程。然而,它们在核事件中的参与引起了广泛关注。有几种 IP 分子与基因调控因子、染色质重塑复合物、mRNA 输出和 DNA 修复机制有关,但在许多情况下,其直接的机制作用仍难以捉摸。本文综述的目的是仅涵盖各种肌醇磷酸盐在核中的作用的最新数据,同时提供真核生物中 IP 合成的逐步概述。
