It is now well established that p62 and NBR1 are selectively degraded by autophagy and can act as cargo receptors or adaptors for the autophagic degradation of ubiquitinated substrates. Research on autophagy in plants is also well under way, but the mechanism by which target substrates are sequestered for autophagic degradation has not been elucidated. The uncharacterized plant protein Q9SB64 shares ...
