The U-box is a highly conserved domain recently identified at the C terminus of yeast UFD2, an E4 ubiquitination factor. In yeast, UFD2 is the only U-box-containing protein, but there are two UFD2 homologs and several other proteins containing a U-box domain in humans. Intriguingly, a database search revealed 37 predicted proteins containing a U-box in Arabidopsis. The plant U-box (PUB) proteins form five distinct subclasses, suggesting that they play diverse roles. The ARC1 gene from Brassica, required for self-incompatibility, is currently the only PUB gene functionally characterized. Here, we discuss the characteristics and possible functions of the PUB gene family.
