WebUSP8 has been suggested to serve as a negative regulator of autophagy and deubiquitinate SQSTM1/p62 (Peng et al., 2024). The knockdown of USP8 promoted autophagic degradation of SQSTM1/p62 (p62), decreasing the p62 adaptor protein in HEK293T cells. In contrast, the overexpression of USP8 led to an increase in p62 in these cells (Peng et al., 2024).
