## Map Uniprot accession numbers with Entrez Gene identifiers

### Description

drosophila2UNIPROT 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: http://www.ensembl.org/biomart/martview/

### Examples

        x <- drosophila2UNIPROT
        # 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]]
        }
