Predicting functional riboSNitches in the context of alternative splicing

Area of Science:

• Genetics
• Molecular Biology
• Bioinformatics

Background:

• RNA secondary structures are critical for gene expression regulation.
• RiboSNitches are disease-associated SNPs altering pre-mRNA secondary structures.
• While regulatory roles in alternative splicing are known, splice junction regions are understudied.

Purpose of the Study:

• To investigate the role of splice-site mutations in disrupting RNA secondary structures.
• To identify novel riboSNitches within splice junctions.
• To explore the potential of these riboSNitches in regulating alternative splicing.

Main Methods:

• Application of multiple riboSNitch prediction methods for reliable identification.
• Analysis of aberrant 5' and 3' splice site mutations.
• Identification of mutations in cancer-associated genes and those with regulatory RNA structures.

Main Results:

• Novel riboSNitches were identified at splice junctions.
• These mutations demonstrated potential to disrupt RNA secondary structures.
• The findings suggest a link between splice junction riboSNitches and alternative splicing regulation.

Conclusions:

• A novel workflow for predicting alternative splicing-associated riboSNitches was developed.
• Splice junction secondary structures are a potential regulatory mechanism in alternative splicing.
• The identified riboSNitches warrant further experimental validation.
