Quantifying cross-tissue diversity in proteasome complexes by mass spectrometry

Mol Biosyst. 2010 Aug;6(8):1450-3. doi: 10.1039/c004989a. Epub 2010 May 24.

Abstract

The composition of 20S mouse proteasome complexes isolated from mice heart, kidney, liver, lung, thymus and spleen was compared using quantitative mass spectrometry. Significant variety was observed in hybrid classes of immunoproteasomes which may have implications for the use of proteasome targeted inhibitors.
