What is your source of Drosophila protein sequence information?
The sequence data is derived from Flybase version FB_2007_3, October 2007
What is your source of protein-grouping data (Molecular Function, Biological Process, Pathway and Family)?
The data is derived from http://flybase.bio.indiana.edu/ (FLYBASE), http://www.pantherdb.org/ and http://www.pir.uniprot.org/
Why do certain protein IDs appear in GRASP with multiple suffixes?
When a gene gives rise to more than one protein product, each protein product is indicated with a different suffix (ie: PA, PB , etc). We observed that in some cases, two protein products coded by the same gene may show an identical amino acid sequence, but different IDs (eg: CG12428-PA and CG12428-PB). This typically happens when different transcript products of the same gene code for identical protein products.
