background: splicing by overlap extension (soe) pcr is used to create mutation in the coding sequence of an enzyme in order to study the role of specific residues in protein’s structure and function.objectives: we introduced a nested-soe-pcr (n –soe-pcr) in order to increase the specificity and generating mutations in a gene by soe-pcr.  materials and methods: genomic dna from bacillus thermoca...

Splicing sites prediction plays a major role in genomic research of biomedical science. If splicing sites of genomic sequence can be correctly predicted, numerous crucial problems in biomedical area may be resolved naturally. Some typical examples are finding pathogenic factors of serious diseases and developing new gene therapy and so on. The major difficulty in developing the method of predic...

The secondary structure of a pre-mRNA influences a number of processing steps including alternative splicing. Since most splicing regulatory proteins bind to single-stranded RNA, the sequestration of RNA into double strands could prevent their binding. Here, we analyzed the secondary structure context of experimentally determined splicing enhancer and silencer motifs in their natural pre-mRNA c...

Alternative splicing is now commonly thought to affect more than half of all human genes. Recent studies have investigated not only the scope but also the biological impact of alternative splicing on a large scale, revealing that its role in generating proteome diversity may be augmented by a role in regulation. For instance, protein function can be regulated by the removal of interaction or lo...

Alternative splicing is a common mechanism for the generation of multiple isoforms of proteins. It can function to expand the proteome of an organism and can serve as a way to turn off gene expression after transcription. This review focuses on splicing, its regulation and the progress in this field achieved through studies in C. elegans. Recent experiments, including RNA-Seq to uncover and mea...

Alternative splicing is regulated by splicing factors that modulate splice site selection. In some cases, however, splicing factors show antagonistic activities by either activating or repressing splicing. Here, we show that these opposing outcomes are based on their binding location relative to regulated 5' splice sites. SR proteins enhance splicing only when they are recruited to the exon. Ho...

Correction for ‘Dynamic visualization of mRNA splicing variants with a transactivating reporter’ by Si Chen et al. , Chem. Commun. 2021, DOI: 10.1039/d1cc02439f.

As an integrated database, SpliceInfo identifies automatically the conserved sequences in selected exon/intron regions of a gene group. Several modes of mRNA alternative splicing, such as exon skipping, alternative 5'-splicing sites, alternative 3'-splicing sites and mutually exclusive exons are computationally derived and extracted. Finally, for each type of alternative splicing, the flanking ...

The protein Sex-lethal (SXL) controls pre-mRNA splicing of two genes involved in Drosophila sex determination: transformer (tra) and the Sxl gene itself. Previous in vitro results indicated that SXL antagonizes the general splicing factor U2AF65 to regulate splicing of tra. In this report, we have used transgenic flies expressing chimeric proteins between SXL and the effector domain of U2AF65 t...
