丁一倞研究组发布首个多物种转录组G四联体结构数据库
2022年10月25日 · 在所有的RNA结构中,RNA G四联体(RNA G-quadruplex, rG4)是一种重要的RNA三级结构。 它通常富含鸟嘌呤(G-rich)并同时包含Hoogsteen碱基和Watson-Crick碱基。 目前,rG4被证明在转录后调控过程发挥重要作用,包括抑制翻译过程,减弱RNA降解,影响miRNA的结合以及RNA的可变剪切等【1】。 rG4具有明显的序列特征,如典型的rG4为四组三联鸟嘌呤与三个长度不超过7nt的环 (G3N1-7)。 此外,还有一些非经典的rG4结构,如二联鸟嘌 …
RNA G-quadruplexes (rG4s): genomics and biological functions
In this review, we will summarize the innovative high-throughput methods recently developed to detect rG4s on a transcriptome-wide scale, highlight the many novel and important functions of rG4 being discovered in vivo across the tree of life, and discuss the key biological questions to be addressed in the near future. INTRODUCTION
G-Quadruplexes in RNA Biology: Recent Advances and
2021年4月1日 · RNA G-quadruplexes (RG4s) are four-stranded structures known to control gene expression mechanisms, from transcription to protein synthesis, and DNA-related processes.
QUADRatlas: the RNA G-quadruplex and RG4-binding proteins …
2023年1月6日 · RNA G-quadruplexes (RG4s) are non-canonical, disease-associated post-transcriptional regulators of gene expression whose functions are driven by RNA-binding proteins (RBPs). Being able to explore transcriptome-wide RG4 formation and interaction with RBPs is thus paramount to understanding how they a …
RNA G-quadruplexes and stress: emerging mechanisms and …
2024年2月9日 · RNA G-quadruplexes (rG4s) are emerging stress-responsive cis -elements found in both the coding and noncoding transcriptomes. The dynamics of rG4s contribute to different aspects of RNA metabolism from transcription to decay. Cellular stress affects rG4s’ dynamics and the functions of rG4-bearing transcripts.
OrensteinLab/rG4detector - GitHub
We present rG4detector, a convolutional neural network for predicting rG4 folding of any given sequence based on rG4-seq data. rG4-seq experimental protocol was employed to generate transcriptome-wide rG4 maps of human HeLa cells (accession code GSE77282).
