Although the number of RNA-Seq datasets deposited publicly has increased over the past few years, incomplete annotation of the associated metadata limits their potential use. Because of the importance of RNA splicing in diseases and biological processes, we constructed a database called SFMetaDB by curating datasets related with RNA splicing factors. Our effort focused on the RNA-Seq datasets i...

Theory of splicing is an abstract model of the recombinant behaviour of DNAs. In a splicing system, two strings to be spliced are taken from the same set and the splicing rule is from another set. Here we propose a generalised splicing (GS) model with three components, two strings from two languages and a splicing rule from third component. We propose a generalised self assembly (GSA) of string...

An increasing body of evidence indicates that transcription and splicing are coupled and it is accepted that chromatin organization and DNA modification regulate transcription. Little is known, however, about the cross-talk between chromatin structure and splicing. We continue to examine how RNA polymerase II and DNA modifications mediate cross-talk between chromatin structure and splicing (see...

The importance of alternative splicing in the regulation of diverse biological processes is reflected in the growing list of human diseases associated with known or suspected splicing defects. It is becoming evident that alternative splicing plays a particularly important role in neurologic disease, which is perhaps not surprising given the important role splicing plays in generating complexity...

Several known trans-splicing RNA structures were used to define a canonical trans-splicing structure which was then used to perform a computer search of the EMBL nucleotide database. In addition to most known trans-splicing structures, many putative new trans-splicing sites were detected. These were found in a broad range of organisms including the vertebrates. Control experiments indicate that...

We have shown that galectin-1 and galectin-3 are functionally redundant splicing factors. Now we provide evidence that both galectins are directly associated with spliceosomes by analyzing RNAs and proteins of complexes immunoprecipitated by galectin-specific antisera. Both galectin antisera co-precipitated splicing substrate, splicing intermediates and products in active spliceosomes. Protein ...

Many splicing factors in vertebrate nuclei belong to a class of evolutionarily conserved proteins containing argininekerine (RS) or serine/arginine (SR) domains. Previously, we demonstrated the existence of SR splicing factors in plants. In this article, we report on a nove1 member of this splicing factor family from Arabidopsis designated atRSp31. It has one N-terminal RNA recognition motif an...

Introns interrupt the continuity of many eukaryal genes, and therefore their removal by splicing is a crucial step in gene expression. Interestingly, even within Eukarya there are at least four splicing mechanisms. mRNA splicing in the nucleus takes place in two phosphotransfer reactions on a complex and dynamic machine, the spliceosome. This reaction is related in mechanism to the two self-spl...

Sequences in exons can play an important role in constitutive and regulated pre-mRNA splicing. Since exonic splicing regulatory sequences are generally poorly conserved and their mechanism of action is not well understood, the consequence of exonic mutations on splicing can only be determined empirically. In this study, we have investigated the consequence of two cystic fibrosis (CF) disease-ca...
