The exon trapping assay partly discriminates against alternatively spliced exons.
A cosmid containing eight exons of the gene coding for the microtubule-associated tau protein was subjected to the exon trapping assay. All the constitutive exons contained in the cosmid (4, 5, 7 and 9) were efficiently captured regardless of size. Of the four alternatively spliced exons, three (3, 4A and 8) were not isolated by the assay, but the behavior of exon 6 depended on the identity of ...
متن کاملAlu-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...
متن کاملRecognition 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...
متن کاملThe birth of an alternatively spliced exon: 3' splice-site selection in Alu exons.
Alu repetitive elements can be inserted into mature messenger RNAs via a splicing-mediated process termed exonization. To understand the molecular basis and the regulation of the process of turning intronic Alus into new exons, we compiled and analyzed a data set of human exonized Alus. We revealed a mechanism that governs 3' splice-site selection in these exons during alternative splicing. On ...
متن کاملAre 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...
