Protein partners of plant ubiquitin-specific proteases (UBPs)

Abstract Protein deubiquitination is reported as one type of post-translational modification involved in various cellular processes. As one type of deubiquitinases (DUBs), ubiquitin-specific proteases (UBPs) play an extensive and significant role in plant life involving the regulation of plant development and stress responses. However, comprehensive studies are still needed to determine the functional mechanisms, which are largely unclear. Here, we summarized recent progress of plant UBPs and their functional partners, particularly the molecular mechanisms by which UBP works with their partners. We believe that functional analyses of UBPs and their partners will provide new insights into protein deubiquitination and lead to a better understanding of the physiological roles of UBPs in plants.
