A post-splicing complex deposited upstream of each exon-exon junction tags mRNAs for nuclear export and mRNA surveillance. The pre-mRNA is coated with hnRNP proteins. The Spliceosome deposits an ...

RNA splicing is a cellular process that is critical for gene expression. After genes are copied from DNA into messenger RNA, portions of the RNA that don't code for proteins, called introns ...

Biologists have discovered a new type of RNA-splicing regulation that helps to determine which protein-coding exons will be included in messenger RNA transcripts. RNA splicing is a cellular ...
