UniProt maps proteomics peptides from different sources to the proteins' sequences. Using this function, you can search for proteomics peptides that has been map to UniProt proteins. You may also refine your search with modifiers such as data_source, peptide etc. See "Arguments section" for more information.
Usage
rba_uniprot_proteomics_search(
accession = NULL,
data_source = NULL,
taxid = NULL,
upid = NULL,
peptide = NULL,
unique = NULL,
...
)Arguments
- accession
UniProtKB primary or secondary accession(s). You can supply up to 100 accession numbers.
- data_source
Proteomics data source. You can choose up to two of:
- taxid
NIH-NCBI Taxon ID. You can supply up to 20 taxon IDs.
- upid
UniProt Proteome identifier (UPID). You can supply up to 100 UPIDs.
- peptide
Peptide sequence(s). You can supply up to 20 sequences.
- unique
Logical: Should the results be filtered based on the Peptide's uniqueness (the fact that a peptide maps to only 1 protein). If TRUE, Only unique peptides will be returned, if FALSE only un-unique peptides will be returned; If NULL (default) the results will not be filtered based on this.
- ...
rbioapi option(s). See
rba_options's arguments manual for more information on available options.
Value
A list Where each element correspond to a UniProt protein and proteomics peptides are organized under the "features" sub-list.
Details
Note that this is a search function. Thus, you are not required to fill
every argument; You may use whatever combinations of arguments you see
fit for your query.
