Proteolysis 6 (PRT6) encodes a ubiquitin E3 ligase belonging to the N-end rule pathway of targeted protein degradation, which is a specialised subset of the ubiquitin proteasome system [1]. In Arabidopsis, at least two N-recognins (E3 ubiquitin ligases) with different substrate specificities exist, namely PROTEOLYSIS1 (PRT1) and PRT6 [2].

A number of them are thought to carry a distinctive five-residue motif termed the proteasome-interacting motif (PIM), which may have a biologically significant role in protein delivery to proteasomes and recruitment of proteasomes to transcription sites [5].
