Characterization and analysis of the composition and dynamics of the mammalian riboproteome

The present invention relates to methods for identifying compounds that modulate the translation machinery and methods of diagnosing cancer related to deregulation of the translation machinery. In particular, the methods and diagnostic tests include determining an association between one or more targets and one or more components of the riboproteome and treating a subject with cancer by administering a compound that modulates the association between one or more targets and one or more components of the riboproteome.
