Sequestosome-1 is a protein that in humans is encoded by the SQSTM1 gene. ^{[5] [6] [7]} Also known as the ubiquitin-binding protein p62, ^[8] it is an autophagosome cargo protein that targets other proteins that bind to it for selective autophagy. By interacting with GATA4 and targeting it for degradation, it can inhibit GATA-4 associated senescence and senescence-associated secretory phenotype. ^[9]

Mutations in SQSTM1 are a common cause of Paget's disease of bone. ^[10]

Sequestosome 1 has been shown to interact with:
