Abstract excerpt

Mitogen activated protein kinase kinase kinase 18 (MAPKKK18) mediated signaling cascade plays important roles in Arabidopsis drought stress tolerance. However, the post-translational modulation patterns of MAPKKK18 are not characterized. In this study, we found that the protein level of MAPKKK18 was tightly controlled by the 26S proteasome. Ubiquitin ligases RGLG1 and RGLG2 ubiquitinated MAPKKK18 at lysine...
