Target description

Sequestosome-1 (UniProt: Q13501; also known as EBI3-associated protein of 60 kDa, EBIAP, p60, Phosphotyrosine-independent ligand for the Lck SH2 domain of 62 kDa, Ubiquitin-binding protein p62) is encoded by the SQSTM1 (also known as ORCA, OSIL) gene (Gene ID: 8878) in human. p62, also known as SQSTM1, is a multi-domain signaling scaffold protein that is Ubiquitously expressed and is involved in numerous critical cellular functions such as autophagy, apoptosis and inflammation. It serves as an autophagy receptor that participates in selective macroautophagy and acts as a bridge between polyubiquitinated cargo and autophagosomes. It acts as a cargo receptor by detecting ubiquitinated substrates using its UBA domain, aggregating them through PB1-mediated homo-polymerization and attaching them to the autophagosome by association with LC3. p62 can undergo phosphorylation at multiple sites by various kinases. Phosphorylation at serine 24 in the PB1 domain by PKA is shown to regulate p62 polymerization and interaction partner binding profile. Mutations in SQSTM1 gene have been linked to Paget disease of bone that is characterized by increased bone turnover affecting one or more sites throughout the skeleton and makes them more susceptible to fractures.
