Use this function to retrieve a UniProt Entry by it's UniProt accession. You can also use "isoform" or "interaction" arguments to retrieve isoforms or interactor proteins of that entry. Note that in one function call you can only set none or only one of "isoform" or "interaction" as TRUE, not both of them.

rba_uniprot_proteins(accession, interaction = FALSE, isoforms = FALSE, ...)



UniProtKB primary or secondary accession.


Logical: (default = FALSE) Only retrieve interaction information of your supplied UniProt entity?


Logical: (default = FALSE) Only retrieve isoforms of your supplied UniProt entity?


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


A list that contains UniProt protein informations with your supplied accession.
