This is a resource for software and information about alternative splicing. Contributions welcome...
- Skipped exon or cassette exon (SE): An exon can be retained or spliced out of the primary transcript.
- Mutually exclusion exons (MXE): One of two exons is retained in mRNA splicing, but not both.
- Alternative 5' splice site (A5SS): An alternative 5' splice junction (donor site) is used that changes the 3' boundary of the upstream exon.
- Alternative 3' splice site (A3SS): An alternative 3' splice junction (acceptor site) is used that changes the 5' boundary of the downstream exon.
- Retained intron (RI): A sequence may be spliced out as an intron or retained, and there are no flanking introns.
