Components of the ubiquitin-proteasome system and substrates localize to the centrosome (composed of the marked PCM and centrioles) in a conserved manner. Representative examples. of ubiquitin-proteasome components (shown above the dashed line) and substrates (shown below the dashed line) are color-coded according to the organism in which centrosomal localization was observed. Citations for individual reports are provided in brackets.
