Use this function to search genomic coordinates of UniProt entries. You may also refine your search with modifiers such as chromosome, taxon id etc. See "Arguments section" for more information.


  accession = NULL,
  chromosome = NULL,
  ensembl_id = NULL,
  gene = NULL,
  protein = NULL,
  taxid = NULL,
  location = NULL,



UniProtKB primary or secondary accession(s). You can supply up to 100 accession numbers.


chromosome name, such as "X", "Y", 1, 20, etc. You can supply up to 20 values.


Ensembl Stable gene ID, transcript ID or translation ID. You can supply up to 20 IDs.


UniProt gene name(s). You can supply up to 20 gene names.


UniProt protein name


NIH-NCBI Taxon ID. You can supply up to 20 taxon IDs.


Genome location range such as "58205437-58219305"


rbioapi option(s). See rba_options's arguments manual for more information on available options.


List where each element corresponds to one UniProt entity returned by your search query. The element itself is a sub-list containing that protein's coordinates information.


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.
