Using this function you can retrieve genomic Coordinates of a Protein by either providing the protein's UniProt accession or it's ID in a cross-reference database (Ensembl, CCDC, HGNC or RefSeq). You should supply either 'accession' alone or 'db_type' and 'db_id' together.


rba_uniprot_coordinates(accession = NULL, db_type = NULL, db_id = NULL, ...)



UniProtKB primary or secondary accession.


cross-reference database name, Should be one of: "Ensembl", "CCDC", "HGNC" or "RefSeq".


Protein's ID in the cross-reference database


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


A list with genome coordinates of your supplied protein.
