Map Uniprot accession numbers with Entrez Gene identifiers

Description

hthgu133aUNIPROT is an R object that contains mappings between Entrez Gene identifiers and Uniprot accession numbers.

Details

This object is a simple mapping of Entrez Gene identifiers http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=gene to Uniprot Accessions.

Mappings were based on data provided by: Entrez Gene ( ftp://ftp.ncbi.nlm.nih.gov/gene/DATA ) on 2009-Mar11

Examples

    x <- hthgu133aUNIPROT
    # Get the entrez gene IDs that are mapped to an Uniprot ID
    mapped_genes <- mappedkeys(x)
    # Convert to a list
    xx <- as.list(x[mapped_genes])
    if(length(xx) > 0) {
      # Get the Uniprot IDs for the first five genes
      xx[1:5]
      # Get the first one
      xx[[1]]
    }
