Intronic and exonic sequences modulate 5' splice site selection in plant nuclei.
Pre-mRNA transcripts in a variety of organisms, including plants, Drosophila and Caenorhabditis elegans, contain introns which are significantly richer in adenosine and uridine residues than their flanking exons. Previous analyses using exonic and intronic replacements between two nonequivalent 5'splice sites in the 469 nt long rbcS3A intron 1 provided the first evidence indicating that, in bot...
متن کاملNew Methods for Splice Site Recognition
Splice sites are locations in DNA which separate protein-coding regions (exons) from noncoding regions (introns). Accurate splice site detectors thus form important components of computational gene finders. We pose splice site recognition as a classification problem with the classifier learnt from a labeled data set consisting of only local information around the potential splice site. Note tha...
متن کاملPyrimidine tracts between the 5' splice site and branch point facilitate splicing and recognition of a small Drosophila intron.
The minimum size for splicing of a vertebrate intron is approximately 70 nucleotides. In Drosophila melanogaster, more than half of the introns are significantly below this minimum yet function well. Such short introns often lack the pyrimidine tract located between the branch point and 3' splice site common to metazoan introns. To investigate if small introns contain special sequences that fac...
متن کاملIntron Retention in the Alternatively Spliced Region of RON Results from Weak 3’ Splice Site Recognition
The RON gene encodes a tyrosine kinase receptor for macrophage-stimulating protein. A constitutively active isoform that arises by skipping of exon 11 is expressed in carcinomas and contributes to an invasive phenotype. However, a high proportion of the mRNA expressed from the endogenous gene, or from transfected minigenes, appears to retain introns 10 and 11. It is not known whether this repre...
متن کاملSecondary structure is required for 3′ splice site recognition in yeast
Higher order RNA structures can mask splicing signals, loop out exons, or constitute riboswitches all of which contributes to the complexity of splicing regulation. We identified a G to A substitution between branch point (BP) and 3' splice site (3'ss) of Saccharomyces cerevisiae COF1 intron, which dramatically impaired its splicing. RNA structure prediction and in-line probing showed that this...
