Using this function you can search and retrieve orthologs of given gene(s), and optionally return the corresponding position in the target organisms' protein sequences.

  type = "all",
  target_organisms = NULL,
  seq_pos = NULL,
  include_msa = NULL,



Character vector of genes identifiers with maximum length of 10 or only one if seq_pos is supplied. Can be any of: Ensemble gene ID, Ensemble protein ID, Ensemble transcript ID, Entrez gene ID, gene symbol, NCBI GI, HGNC ID, International protein index ID, NCBI UniGene ID, UniProt accession and/or UniProt ID.


(numeric) NCBI taxon ID of the organism of your supplied genes. run rba_panther_info with argument 'what = "organisms"' to get a list of PANTHER's supported organisms.


Ortholog types to return. either "all" (default) or "LDO" to only return least diverged orthologs.


(numeric) NCBI taxon ID(s) to filter the results. run rba_panther_info with argument 'what = "organisms"' to get a list of PANTHER's supported organisms.


(Numeric) A position in the protein's sequence of the supplied gene. should be in the range of the protein's length.


(Logical) Only if a sequence position is supplied, should MSA (Multiple Sequence Alignment) information be included in the results?


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


A data frame with Orthologs information.
