Atlas Build
|
Name of PeptideAtlas build, usually includes: organism,
the lower limit PeptideProphet probability limit, and the chromosomal/protein
database mapped to. (For example,
Human_P0.9_Ens26_NCBI35
indicates human organism, atlas is composed of peptides with PeptideProphet probabilities
greater than 0.9, mapped to Ensembl human build version 26 which is based on NCBI genome assembly 35.)

Biosequence Name
|
In PeptideAtlas, Biosequence Name refers to the protein name that the peptide has been mapped to.
A given peptide sequence may have been found in more than one protein or more than once in the
same protein. (For example, human peptide sequence ACNPQYAGAIVVHCSAGVGR
maps to Ensembl Biosequence Names
ENSP00000342783, ENSP00000314568, ENSP00000348468, ENSP00000216877,
and ENSP00000351559 .

|
Best Probability
|
All peptide identifications have been put through the PeptideProphet program
to assign identification probabilities. The best probability is the best
P observed for the peptide sequence.
|
|
Exon spanning
|
Peptide spans exons if sequence maps to both sides of an intron.
|
|
Number of Protein Mappings
|
Number of proteins the peptide sequence has been identified within.
|
|
Number of Times Observed
|
The number of times a peptide sequence has been identified in all experiments.
|
|
Number of Unique Locations on Genome
|
The number of unique chromosomal locations for the mapped peptide sequence.
If a peptide sequence has not been found in the protein database, this value will be
zero and there will not be a Biosequence Name for this peptide.
|
|
Peptide Name/Accession
|
The PeptideAtlas designated name consists of PAp followed by 8 numbers.
Each accession corresponds to a unique peptide sequence.
|
|
Sample
|
A description of the experiment including details such as extraction, digestion, preparation.
(Sample annotation is still in progress, but expect to see minimal description of sample
for all samples, and more information for those published or declared public).
|
|
Start/End Position
|
Chromosomal coordinates of the peptide sequence.
