All eukaryotes rely on selective proteolysis to control the abundance of key regulatory
proteins and maintain a healthy and properly functioning proteome. Most of this turnover is …

Post-translational modifications (PTMs) are at the heart of many cellular signaling events.
Apart from a single regulatory PTM, there are also PTMs that function in orchestrated …

Plants encounter a variety of stresses and must fine-tune their growth and stress-response
programs to best suit their environment. BES1 functions as a master regulator in the …
