p62

Sequestosome-1; SQSTM1

p62 (SQSTM1 or Sequestosome 1 ), a ubiquitous and multifunctional protein, can direct ubiquitinated proteins to the proteasome or the growing autophagosome. p62 serves as an essential adaptor to identify and deliver specific organelles and protein aggregates to autophagosomes for degradation, a process known as selective autophagy.

    P62-mediated mitophagy inducer (PMI) is a P62-mediated mitophagy activator. P62-mediated mitophagy inducer activates mitochondrial autophagy without recruitment of Parkin or collapse of the mitochondrial membrane potential and remains active in cells lacking a fully functional PINK1/Parkin pathway. P62-mediated mitophagy inducer serves as a pharmacological tool to study the molecular mechanisms of mitosis, avoiding toxicity and some of the non-specific effects associated with the sudden dissipation of mitochondria lacking membrane potential.
