rba_uniprot_ptm_search {rbioapi}

Search Post-Translational Modification in UniProt

Description

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_ptm_search(
  accession = NULL,
  ptm = 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.

ptm

Post-translational modification name

data_source

Proteomics data source. You can choose up to two of:

• "MaxQB"

• "PeptideAtlas"

• "EPD"

• "ProteomicsDB"

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.

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.

Value

A list Where each element correspond to a UniProt protein and post-translational modification are organized under the "features" sub-list.
