ProteomeCommons.org seems to once have been a resource for raw proteomics data. Thought, the website now offers gardening tools. It seems to be hacked. Does anyone know whether the data is still available somewhere?
According to Lars Juhl Jensen on a Biostars forum,
The Proteome Commons Tranche sadly shut down around 2013 due to lack of funding. It is a good example why important bioinformatics infrastructure needs dedicated funding and should not have to operate out of research grants for individual groups.
They seem to have lost the domain name. I believe all the data from that project is now on the UCSD site
