N2 - As a step in their turnover proteins in eukaryotic cells are coupled to a small protein, ubiquitin, before they are recognised by 26S proteasomes and degraded. However, cells also contain many deubiquitinating enzymes, which can rescue proteins by cleaving off the ubiquitin chains. Here we report that three ubiquitin binding proteins, Rhp23, Dph1 and Pus1, from fission yeast can protect multiubiquitin conjugates against deubiquitination. This protection depends on the ubiquitin binding domains and may promote degradation of ubiquitinated proteins.
