p62 is a multidomain protein that contains different kinds of protein-protein interaction domains, including an N-terminal PB1 domain, a ZZ-type zinc finger domain, a nuclear localization signal (NLS), an export motif (NES), the LC3-interacting region (LIR), the KEAP1-interacting region (KIR), and a C-terminal Ub-associated domain (UBA). p62 is involved in the degradation of protein aggregates and cytoplasmic bodies via selective autophagy through its PB1, LIR, and UBA domains to maintain homeostasis in the cell. Moreover, NES, NLS, KIR, and ZZ...
