Data on the identity of non-canonical complexes formed from proteasome subunits in vivo

The dataset presented here represents analysis supplied by the local proteomics core facility on samples submitted to it in support of the article “Assembly of proteasome subunits into non-canonical complexes in vivo” Hammack and Kusmierczyk (2016) [1]. This article provides the detailed protein contents of gel slices, cut from non-denaturing polyacrylamide gels, containing distinct protein complexes visualized following gel staining. The identification of the protein contents of these complexes was carried out by liquid chromatography tandem mass-spectrometry (LC–MS/MS).
