Co-transcriptional commitment to alternative splice site selection.
Production of mRNA in eukaryotic cells involves not only transcription but also various processing reactions such as splicing. Recent experiments have indicated that there are direct physical connections between components of the transcription and processing machinery, supporting previous suggestions that pre-mRNA splicing occurs co-transcriptionally. Here we have used a novel functional approa...
متن کاملSubstances that can change alternative splice-site selection.
Alternative pre-mRNA splicing is an important element in eukaryotic gene expression, as most of the protein-coding genes use this process to generate multiple protein isoforms from a single gene. An increasing number of human diseases are now recognized to be caused by the selection of 'wrong' alternative exons. Research during the last few years identified a number of low-molecular-mass chemic...
متن کاملAlternative pre-mRNA splicing: factors involved in splice site selection.
The protein-coding regions of most vertebrate genes are split, giving rise to primary transcripts containing introns and exons; the latter must be spliced in the nucleus to form the mature mRNA, which then moves to the cytoplasm for translation. Pre-mRNA splicing, the process of intron removal and exon joining, represents an important function within the nucleus, and elucidation of the mechanis...
متن کاملOur favourite alternative splice site.
Alternative splicing is a widespread mechanism in mammals that generates several mRNAs from one gene, thereby creating genetic diversity of the genome. Variant splice patterns are often specific to different stages of development or particular tissues, and alternative splicing defects are being more frequently detected in genetic diseases and cancers. The increasingly important role of alternat...
متن کاملCommitment to splice site pairing coincides with A complex formation.
Differential recognition of exons by the spliceosome regulates gene expression and exponentially increases the complexity of metazoan proteomes. After definition of the exons, the spliceosome is activated by a series of sequential structural rearrangements. Formation of the first ATP-independent spliceosomal complex commits the pre-mRNA to the general splicing pathway. However, the time at whic...
