Overview
JuncForge is a computational pipeline for designing qPCR primer pairs that span cryptic exon (CE) splice junctions. It targets applications in RNA splicing research, including studies of TDP-43 loss of function and cryptic exon inclusion in neurodegeneration.
What it does
Given GenBank files annotating a cryptic exon within an intron, the pipeline:
- Locates CE features and their left/right junctions
- Designs primer pairs via Primer3 with junction-spanning constraints
- Filters candidates with pair-wise BLAST against genome and curated RefSeq mRNA
- Retains only primers expected to amplify the CE-containing transcript
Tech stack
Python, Primer3, BLAST
