Detection of ubiquitinated peroxisomal proteins in yeast

Abstract

Ubiquitination is involved in different aspects of peroxisome formation, maintenance, and degradation. Consequently, simple methods for detecting ubiquitinated peroxisomal proteins are extremely useful in peroxisomal research. Here, we describe an immunoprecipitation-based technique that can be used to assess peroxisomal protein ubiquitination in yeast.
