Abstract

The ubiquitin-proteasome pathway for intracellular proteolysis is involved in a series of cellular and molecular functions, including the degradation of bulk proteins, cell cycle control, DNA repair, antigen presentation, vesicle transport and the regulation of signal transudation pathways and transcription. Considering this variety of cell biological processes, it is puzzling that until recently only very few proteins were known to possess the ability to interact specifically with ubiquitin chains. However, several ubiquitin binding proteins have now been identified and the binding domains have been characterised on both the functional and structural levels. One example of a widespread ubiquitin binding module is the ubiquitin associated (UBA) domain. Here, we discuss the approximately 15 UBA domain containing proteins encoded in the relatively small genome of the fission yeast Schizosaccharomyces pombe. The proteins display remarkable differences in their domain organisation, indicating that these potential ubiquitin binding proteins are involved in various cell activities.
