The autophagic receptor p62 recognizes arginylated (Nt-R) substrates through its ZZ domain (p62ZZ). Here the authors identify a p62 auto regulatory mechanism and provide structural insights into the selective recognition of Nt-R by p62ZZ and further show that Nt-R binding stimulates p62 oligomerization and macroautophagy.
