Fig. 2. T7 RNA processing. RNA processing in eukaryotic systems, schematically shown in Fig. 3, is of paramount importance. It involves both the elimination of the region preceding the 5’ end of the mature mRNA (29) and the excision, by “splicing” of the internal regions not coding ...
The ubiquity of RNA-seq has led to many methods that use RNA-seq data to analyze variations in RNA splicing. However, available methods are not well suited for handling heterogeneous and large datasets. Such datasets scale to thousands of samples across dozens of experimental conditions, exhibit ...
For mosteukaryoticgenes(and some prokaryotic ones), the initialRNAthat is transcribed from a gene'sDNAtemplate must be processed before it becomes a maturemessenger RNA(mRNA) that can direct thesynthesis ofprotein. One of the steps in this processing, called RNAsplicing, involves the removal or ...
Targeting splicing dysregulations To maintain uncontrolled cell growth and aberrant gene expression, the RNA processing machinery is also frequently altered during tumorigenesis [6,7]. RNA splicing is one of the essential steps for gene expression and is necessary for producing diverse transcripts require...
Here, we describe enhanced silencing phenotype (esp) mutants in Arabidopsis thaliana that reveal how proteins associated with RNA processing and 3' end formation can influence RNA silencing. These proteins were a putative DEAH RNA helicase homologue of the yeast PRP2 RNA splicing cofactor and ...

selective splicing, transport, localization, and translation, thereby forming a complex RNA-RBP regulatory network. Mutations and abnormal expression of RBPs can impact various steps in RNA processing, consequently altering the functions of target RNAs. Therefore, genetic alterations and abnormal expression...

Functional RNA secondary structure is important for the pre-mRNA processing including splicing, cleavage and polyadenylation, and RNA editing. Here the authors present a catalog of conserved long-range RNA structures in the human transcriptome by defining pairs of conserved complementary regions (PCCR) ...
