How to search posttranslational modification sites of a certain protein:

- via sequence (case-insensitive): It is possible to use the entire protein sequence, but also short parts of it (e.g., peptide sequences).

- via gene symbol, name, or description

- via unique accession numbers. The corresponding databases for each species are the following:
Homo sapiens: IPI Human Database Version 3.24 or Swissprot Database Version 54.8
Mus musculus: IPI Mouse Database Version 3.69 or Swissprot Database Version 57.12
Drosophila melanogaster: FlyBase 5.4 or Swissprot Database Version 55.2
Caenorhabditis elegans: WormPep200 or Swissprot Database Version 57.12
Saccharomyces cerevisiae: Yeast SGD or Swissprot Database Version 57.12

In the case of IPI databases, you do not have to use version numbers for the accession numbers.
