Splicing and Junction Mapping

Visualisation of the transcriptome relative to a reference genome is fraught with sparsity. This is due to RNA sequencing (RNA-Seq) reads being predominantly mapped to exons that account for...

RNA editing leads to post-transcriptional variation in protein sequences and has important biological implications. Researchers from the St. Jude Children’s Research Hospital sought to elucidate the...

Alternative RNA isoforms are defined by promoter choice, alternative splicing, and polyA site selection. Although differential isoform expression is known to play a large regulatory role in eukaryotes, it has proved challenging to study with standard short-read RNA-seq because of ...

A simplistic understanding of the central dogma falls short in correlating the number of genes in the genome to the number of proteins in the proteome.

Fusion genes are both useful cancer biomarkers and important drug targets. Finding relevant fusion genes is challenging due to genomic instability resulting in a high number of passenger events...

Transcription of eukaryotic genomes involves complex alternative processing of RNAs. Sequencing of full-length RNAs using long reads reveals the...

Alternative splicing removes intronic sequences from transcripts in alternative ways to produce different forms (isoforms) of mature mRNA. The composition of expressed transcripts and their alternative forms give specific functionalities to cells in a particular...

The identification of gene fusions from RNA sequencing data is a routine task in cancer research and precision oncology. However, despite the...

A new statistical model from Xi’an Jiaotong-Liverpool University aims to solve the problem of isoform ambiguity related to RNA modifications. The paper, published on 2 November in the leading...

Alternative splicing plays a major role in regulating the functional repertoire of the proteome. However, isoform-specific effects to protein-protein interactions (PPIs) are usually overlooked, making it impossible to judge the functional role of individual exons on a systems biology level. ...
