长链非编码rna (lncRNAs)是在细胞中发现的长度超过200个核苷酸的转录物,缺乏蛋白质编码功能。它们的功能与其与rna结合蛋白(rbp)和核酸的相互作用密切相关。核lncrna已被广泛研究,揭示了具有结构和调控作用的复合物,使基因组织和控制转录成为可能。细胞质中的lncrna还不太清楚,但越来越多的证据表明它们也形成具有不同结构和调节功能的复合物。在这里,我们回顾了我们目前对细胞质lncRNA和细胞质lncRNA复合物控制的不同水平的基因调控的了解,包括mRNA的转换、翻译、蛋白质稳定性、胞质因子的海绵作用和信号通路的调节。最后,我们讨论了未来需要全面研究lncrna生物学的研究领域,以进一步了解lncrna对生理的影响,并设计以lncrna为中心的治疗策略。
Long noncoding RNAs (lncRNAs) are transcripts longer than 200 nucleotides found throughout the cell that lack protein-coding function. Their functions are closely linked to their interaction with RNA-binding proteins (RBPs) and nucleic acids. Nuclear lncRNAs have been studied extensively, revealing complexes with structural and regulatory roles that enable gene organization and control transcription. Cytoplasmic lncRNAs are less well understood, but accumulating evidence indicates that they also form complexes with diverse structural and regulatory functions. Here, we review our current knowledge of cytoplasmic lncRNAs and the different levels of gene regulation controlled by cytoplasmic lncRNA complexes, including mRNA turnover, translation, protein stability, sponging of cytosolic factors, and modulation of signaling pathways. We conclude by discussing areas of future study needed to investigate comprehensively the biology of lncRNAs, to further understand the impact of lncRNAs on physiology and design lncRNA-centered therapeutic strategies.
