You should now be back looking at the webpage containing the paper abstract page. If not go to the browser window containing the protein entry and click the browser 'Back Button' once (maybe twice), or click this link.
Finding the DNA sequence
We will now find the DNA sequence associated with the paper.
  1. In the Related Information list click on the 'Nucleotide (RefSeq)' link.
  2. You should get a list of sequences. Find NM_031831 - Rattus norvegicus reticulon 4 (Rtn4), mRNA (it should be about number 8) and click on the associated link. You should now be looking at the DNA sequence (it should look similar to the image below).
