The neXtProt peptide uniqueness checker: a tool for the proteomics community

Bioinformatics. 2017 Nov 1;33(21):3471-3472. doi: 10.1093/bioinformatics/btx318.

Abstract

Summary: The neXtProt peptide uniqueness checker allows scientists to define which peptides can be used to validate the existence of human proteins, i.e. map uniquely versus multiply to human protein sequences taking into account isobaric substitutions, alternative splicing and single amino acid variants.

Availability and implementation: The pepx program is available at https://github.com/calipho-sib/pepx and can be launched from the command line or through a cgi web interface. Indexing requires a sequence file in FASTA format. The peptide uniqueness checker tool is freely available on the web at https://www.nextprot.org/tools/peptide-uniqueness-checker and from the neXtProt API at https://api.nextprot.org/.
