Proteolytic Proteoforms: Elusive Components of Hormonal Pathways?

Trends Plant Sci. 2020 Apr;25(4):325-328. doi: 10.1016/j.tplants.2020.01.002. Epub 2020 Feb 11.


Hormonal pathways often converge on transcriptional repressors that can be degraded by the proteasome to initiate a response. We wish to draw attention to developments in a less-explored proteolytic branch called 'limited proteolysis' that, in addition to the classical proteolytic pathways, seems to regulate auxin and ethylene signaling.

Keywords: auxin; ethylene; phytohormone signaling; processing bodies; proteoforms; proteolysis.
