GWIPS-viz as a tool for exploring ribosome profiling evidence supporting the synthesis of alternative proteoforms.

ABSTRACT: The boundaries of protein coding sequences are more difficult to define at the 5' end than at the 3' end due to potential multiple translation initiation sites (TISs). Even in the presence of phylogenetic data, the use of sequence information only may not be sufficient for the accurate identification of TISs. Traditional proteomics approaches may also fail because the N-termini of newly synthesized proteins are often processed. Thus ribosome profiling (ribo-seq), producing a snapshot of the ribosome distribution across the entire transcriptome, is an attractive experimental technique for the purpose of TIS location exploration. The GWIPS-viz (Genome Wide Information on Protein Synthesis visualized) browser (http://gwips.ucc.ie) provides free access to the genomic alignments of ribo-seq dat
