Arabidopsis PROTEASOME REGULATOR1 is required for auxin-mediated suppression of proteasome activity and regulates auxin signalling.
- AnnotationPROTEASOME REGULATOR1 (PTRE1) is a positive regulator of the 26S proteasome. Ptre1 mutants are insensitive to auxin-mediated suppression of proteasome activity show diminished auxin-induced degradation of Aux/IAA proteins and display auxin-related phenotypes. [PTRE1], PTRE1 is localized to the plasma membrane, the nucleus and the cytoplasm.
- FunctionPTRE1 positively influences 26S proteasome activity and reduces 20S proteasome activity in Arabidopsis plants.
