Ubiquitin C-terminal hydrolases (UCHs) are a subset of de-ubiquitinating proteases that release covalently linked ubiquitin (Ub), and as such play essential roles in recycling Ub and reversing the action of Ub conjugation. We show here that two related Arabidopsis UCHs, UCH1, and UCH2, are important for shoot development. The UCH1 and 2 genes are ubiquitously expressed, with the corresponding proteins present in both the cytoplasm and nucleus. Unlike their animal and fungal counterparts, we… CONTINUE READING
