How can I download all the proteins in the human proteome? Do I use BioMart?
While BioMart can export protein sequences, the entire protein set for any species can be downloaded directly from our ftp site. Please use this method of download, as BioMart cannot handle the very large query of an entire proteome.
If you do need a customized sequence header, consider splitting the BioMart query into chromosomes. Make sure the compressed webfile/notify by email option is selected.
