Background: p62/SQSTM1
Abnormal function of p62/SQSTM1 is associated with a range of disease states such as neurodegeneration, cancer, and metabolic disorders (2). Mutations in the p62/SQSTM1 sequence have been linked to Paget's disease of the bone, amyotrophic lateral sclerosis, and frontotemporal lobar degeneration. In Parkinson's disease, p62/SQSTM1 has been linked to microglia activation and subsequent neuroinflammation (3). Functionally, p62/SQSTM1 is involved in a broad range of cellular processes such as amino acid sensing by interaction with mTORC1, oxidative stress response through interaction with Keap1, and targeting cargo for autophagy by interacting with ubiquitin labeled proteins (1).
To induce selective autophagy, p62/SQSTM1 forms long oligomers or helical filaments which interact with LC3 and ubiquitin labeled proteins and lead to the initiation of the autophagosome formation (2). p62/SQSTM1 is not only a selective autophagy receptor but also an autophagy substrate, as its engulfed by the autophagosome and degraded by the autophagolysosome. Monitoring LC3 levels is the standard for assessing autophagic flux, however monitoring p62/SQSTM1 levels by Western blot in the presence and absence of autophagy inhibitors (e.g., Chloroquine) is also a common practice (4). Besides its activity as a selective autophagy receptor, p62/SQSTM1 also plays a role as an adaptor in signaling cascades leading to NFkB activation downstream of TNF-R, IL-1 beta R, TrkA and p75NTR. Briefly, for NFkB signaling downstream of the TNF-R activation, p62/SQSTM1 engages RIP1 kinase and PKC iota/lambda through the ZZ and PB1 domains, respectively (5).
