Object: Starting with an organism and a protein, find a protein sequence and gene coding region. Example: Find the protein sequence and gene coding region for pathogenicity factor listeriolysin O from the bacterium Listeria monocytogenes . Searching for gene and protein information Begin the search in Gene , because it has less redundancy than Protein (this same search in Protein retrieves over 1000 records). Search: Listeria monocytogenes[organism] AND listeriolysin O[ protein name] (see Searchable fields in Gene ) One record, for gene symbol hly , is retrieved. It is associated with an NC_ accession number (specifying a complete genomic molecule that is usually a reference assembly; see RefSeq accession numbers and molecule types ). To find the gene coding sequence , look at the Genomic regions, transcripts, and products section or the NCBI Reference Sequences ( RefSeq ) section of the Gene record: Clicking on the GenBan k link disp
