Alternative splicing and tumor progression

Following growing of knowledge regarding splicing regulation, several approaches have been developed to compensate for the effect of deleterious mutations and to restore sufficient amounts of functional protein.

Previous article Next article. This regulation is under control of the spliceosome and several splicing factors are also required to modulate the alternative usage of splice sites. Current usage metrics About article metrics Return to article.

Splicing factors and spliceosome components recognize splicing signals and regulatory sequences of the pre-mRNAs. Services Articles citing this article CrossRef 2. Abstract Alternative 3′-terminal exons, which use intronic polyadenylation sites, are generally less conserved altwrnatif expressed at lower levels than the last exon of genes.

Most of protein-coding human genes are subjected to alternative pre-mRNA splicing.
