It was first identified as a protein that binds to the SH2 domain of p56Lck (5) and independently found to interact with PKCζ (6,7). SQSTM1 was subsequently found to interact with ubiquitin, providing a scaffold for several signaling proteins and triggering degradation of proteins through the proteasome or lysosome (8). Interaction between SQSTM1 and TRAF6 leads to the K63-linked polyubiquitination of TRAF6 and subsequent activation of the NF-κB pathway (9). Protein aggregates formed by SQSTM1 can be degraded by the autophagosome (4,10,11). SQSTM1 binds autophagosomal membrane protein LC3\/Atg8, bringing SQSTM1-containing protein aggregates to the autophagosome (12). Lysosomal degradation of autophagosomes leads to a decrease in SQSTM1 levels during autophagy; conversely, autophagy inhibitors stabilize SQSTM1 levels. Studies have demonstrated a link between SQSTM1 and oxidative stress. SQSTM1 interacts with KEAP1, which is a cytoplasmic inhibitor of NRF2, a key transcription factor involved in cellular responses to oxidative stress (3). Thus, accumulation of SQSTM1 can lead to an increase in NRF2 activity. TANK-binding kinase 1 (TBK1) is activated by von Hippel-Lindau (VHL) loss or hypoxia in cancer cells. TBK1 phosphorylates p62\/SQSTM1 on Ser366, which is essential for p62 stability and kidney cancer cell proliferation (13).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nA170; autophagy receptor p62; DMRV; EBI3-associated protein of 60 kDa; EBI3-associated protein p60; EBIAP; FTDALS3; NADGP; ORCA; OSIL; oxidative stress induced like; p60; p62; p62B; PDB3; phosphotyrosine independent ligand for the Lck SH2 domain p62; Phosphotyrosine-independent ligand for the Lck SH2 domain of 62 kDa; sequestosome 1; Sequestosome-1; SQSTM; SQSTM1; Ubiquitin-binding protein p62; ZIP3\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R\nSENSITIVITY: Endogenous\nMW (kDa): 62\nSOURCE: Rabbit","brand":"CST","offers":[{"title":"Default Title","offer_id":46797936885929,"sku":"26317S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-26317s","provider":"Iright","version":"1.0","type":"link"}
