You should cite the sequence files as publications in your resume/CV. A good way to cite this sequence file would be:
1. Caenorhabditis brenneri clone 2C4.08 initiation factor (inf-1) mRNA, partial cds., Chimento,D., Vershon,A.K., Nemeroff,M.E., NCBI, May 11, 2008. Accession # EU637891
http://www.ncbi.nlm.nih.gov/entrez/viewer.fcgi?db=nuccore&id=187476471
In addition, you may also have a protein sequence file. You can find the link to this report in the /protein_id= section of the DNA sequence report. Be sure to cite it as well.
2. Initiation factor [Caenorhabditis brenneri] protein. Chimento,D., Vershon,A.K., Nemeroff,M.E., NCBI, May 11, 2008. Accession # ACD12696
