Input: single peptide or a peptide list (max.5000 sequences)

Peptide Sequence:
Fuzzy mapping settings
Number of unknown amino acids:
Match mass tolerance: Da

Column Descriptions ▲
Searched SequenceThe mapped peptide sequence. * denotes a sequence that matches the input sequence.
When using the fuzzy mapping option, amino acids that are different from the input sequence are highlighted. Furthermore, if a mass tolerance was also set, sequences that match due to common mass modifications are also shown, with multiple mods possible.
ProteinsAn exhaustive list of all protein entries that the peptide sequence maps to, with direct links to PeptideAtlas.
Multiple mappings are separated by the > symbol; identical protein sequences are indicated by the = sign.
Guide to accession prefixes:
ENSP :: Ensembl protein entry
sp| :: UniProtKB/Swiss-Prot protein entry
tr| :: UniProtKB/TrEMBL protein entry
NP_ :: NCBI RefSeq reviewed protein entry
XP_ :: NCBI RefSeq unreviewed protein entry
NX_ :: neXtProt protein entry
IMGT :: Immunoglobulin from IMGT database
CONTRIB_ :: a potentially translated community contributed protein entry
PositionThe location within the protein sequence that the first amino acid of the peptide maps to.
Database SequenceThe reference sequence of the protein at the site of the peptide mapping, including flanking amino acids (a dash indicates the end or start of the protein sequence).
PEFF variants, if present, are highlighted.
nSubsThe number of amino acid substitutions (via PEFF) that were required to achieve the mapping of the input sequence to the protein. A value of zero denotes a perfect match to the native sequence.
% database sequenceA bar that represents how much of the native protein sequence is matched by the input peptide sequence. Inversely proportional to nSubs
The longer the bar, the fewer PEFF substitutions involved in the match.
