Dual-specificity splice sites function alternatively as 5' and 3' splice sites.
As a result of large-scale sequencing projects and recent splicing-microarray studies, estimates of mammalian genes expressing multiple transcripts continue to increase. This expansion of transcript information makes it possible to better characterize alternative splicing events and gain insights into splicing mechanisms and regulation. Here, we describe a class of splice sites that we call dua...
متن کاملIntrinsic differences between authentic and cryptic 5' splice sites.
Cryptic splice sites are used only when use of a natural splice site is disrupted by mutation. To determine the features that distinguish authentic from cryptic 5' splice sites (5'ss), we systematically analyzed a set of 76 cryptic 5'ss derived from 46 human genes. These cryptic 5'ss have a similar frequency distribution in exons and introns, and are usually located close to the authentic 5'ss....
متن کاملIdentification of alternative 5′/3′ splice sites based on the mechanism of splice site competition
Alternative splicing plays an important role in regulating gene expression. Currently, most efficient methods use expressed sequence tags or microarray analysis for large-scale detection of alternative splicing. However, it is difficult to detect all alternative splice events with them because of their inherent limitations. Previous computational methods for alternative splicing prediction coul...
متن کاملComputational prediction of efficient splice sites for trans-splicing ribozymes.
Group I introns have been engineered into trans-splicing ribozymes capable of replacing the 3'-terminal portion of an external mRNA with their own 3'-exon. Although this design makes trans-splicing ribozymes potentially useful for therapeutic application, their trans-splicing efficiency is usually too low for medical use. One factor that strongly influences trans-splicing efficiency is the posi...
متن کاملProcessing of chimeric introns in dicot plants: evidence for a close cooperation between 5' and 3' splice sites
Splice sites of vertebrate introns are generally not recognized in plant cells. Several lines of evidences have led to the proposal that the mechanism of 3' splice site selection differs in plants and animals (K. Wiebauer, J.J. Herrero, and W. Filipowicz, Mol. Cell. Biol. 8:2042-2051, 1988). To gain a better insight into the mechanistic differences between plant and animal splicing, we construc...
