In FScanR: Detect Programmed Ribosomal Frameshifting Events from mRNA/cDNA BLASTX Output

FScanR: an R package to detect Programmed Ribosomal Frameshifting (PRF) events from mRNA/cDNA

‘FScanR’ identifies Programmed Ribosomal Frameshifting (PRF) events from BLASTX output in tab format containing the best hits of targeted mRNA/cDNA sequences against the peptide library of the same species or a close relative.

To acquire the input file with 14 columns in tab-delimited format, which is generated by BLASTX, parameters should be used for BLASTX:

-outfmt '6 qseqid sseqid pident length mismatch gapopen qstart qend sstart send evalue bitscore qframe sframe'

:orange_book: What is Programmed Ribosomal Frameshifting (PRF)?

- From Mauger et al., 2013, FEBS Letters

Ribosomal frameshifting, also known as translational frameshifting or translational recoding, is a biological phenomenon that occurs during translation that results in the production of multiple, unique proteins from a single mRNA. The process can be programmed by the nucleotide sequence of the mRNA and is sometimes affected by the secondary, 3-dimensional mRNA structure. It has been described mainly in viruses (especially retroviruses), retrotransposons and bacterial insertion elements, and also in some cellular genes.
