SQSTM1 oligomerizes by virtue of its PB1 domain. Oligomerization is required for formation of inclusion bodies with ubiquitinated proteins destined for autophagic degradation, and may contribute to phagophore membrane development (Bjorkoy et al, 2005; Ciuffa et al, 2015; Itakura and Mizushima, 2011; reviewed in Lamark et al, 2017).
