p62 as a therapeutic target for tumor

p62/SQSTM1 (hereafter as p62) is a stress-inducible cellular protein, which interacts with various signaling proteins to regulate a variety of cellular functions. Growing lines of evidence supported a critical role of p62 in tumorigenesis, and p62 may become a therapeutic target for tumor. In this review, we summarize biological functions of structural domains of p62, reported bioactive molecules targeting p62, and the relationship between p62 and tumorigenesis.
