Overlapping alternative donor and acceptor sites may have different functional roles: alternative splicing of overlapping acceptor sites mainly leads to microvariations in protein sequences, whereas alternative donor sites often lead to frameshifts and thus either yield major differences in protein sequence and structure, or generate NMD-inducing mRNA isoforms.

We used Bayesian Networks, a state of the art machine learning tool, to accurately distinguish between alternative and constitutive human exons. Using a combination of previously described features and novel ones, we were able to achieve a performance competitive with the state of the art from the literature.

Tag-Based Approaches for the Detection of Cis-Encoded Antisense Transcription

To create a genome-wide catalog of accurate gene expression profiles for mammalian sense-antisense transcripts, we analyzed over 200 publicly available LongSAGE libraries and one Solexa-SAGE library. We found that more than half of the EnsEMBL genes have evidence for antisense transcription throughout mouse development.
