Are all of the human exons alternatively spliced?

Alternative mRNA splicing (AS) is a major mechanism for increasing regulatory complexity. A key concept in AS is the distinction between alternatively and constitutively spliced exons (ASEs and CSEs, respectively). ASEs and CSEs have been reported to be differentially regulated, and to have distinct biological properties. However, the recent flood of RNA-sequencing data has obscured the boundar...

Alu-containing exons are alternatively spliced.

Alu repetitive elements are found in approximately 1.4 million copies in the human genome, comprising more than one-tenth of it. Numerous studies describe exonizations of Alu elements, that is, splicing-mediated insertions of parts of Alu sequences into mature mRNAs. To study the connection between the exonization of Alu elements and alternative splicing, we used a database of ESTs and cDNAs al...

Positive selection in alternatively spliced exons of human genes.

Alternative splicing is a well-recognized mechanism of accelerated genome evolution. We have studied single-nucleotide polymorphisms and human-chimpanzee divergence in the exons of 6672 alternatively spliced human genes, with the aim of understanding the forces driving the evolution of alternatively spliced sequences. Here, we show that alternatively spliced exons and exon fragments (alternativ...

Recognition of Unknown Conserved Alternatively Spliced Exons

The split structure of most mammalian protein-coding genes allows for the potential to produce multiple different mRNA and protein isoforms from a single gene locus through the process of alternative splicing (AS). We propose a computational approach called UNCOVER based on a pair hidden Markov model to discover conserved coding exonic sequences subject to AS that have so far gone undetected. A...

Intronic sequences flanking alternatively spliced exons are conserved between human and mouse.

Comparison of the sequences of mouse and human genomes revealed a surprising number of nonexonic, nonexpressed conserved sequences, for which no function could be assigned. To study the possible correlation between these conserved intronic sequences and alternative splicing regulation, we developed a method to identify exons that are alternatively spliced in both human and mouse. We compiled tw...
