Is there any open proteomics repository like GEO?

Question

[Diwan]

Hello,

I would like to do metaanalysis of proteomics data. Is there any publicly available proteomics database or repository like GEO/arrayexpress?

Based on google search, I found: http://www.ebi.ac.uk/pride/archive/

Do you know of any other repositories/db?

Thanks

Diwan

I think PeptideAtlas might also have mass-spec data for samples that potentially have meta-data, but PRIDE is the main one that comes to mind.

It is much harder to find large, publicly available proteomics datasets (unless you count protein arrays: for example, I think TCGA has RPPA protein array data and there is also this website that can do some protein array analysis: http://app1.bioinformatics.mdanderson.org/tcpa/_design/basic/index.html )

How about the Protein DataBank?

There's also Entrez Protein.
