The ubiquitin-proteasomal system and the autophagy-lysosome system are two major degradation systems in mammalian cells. Ubiquitin not only regulates proteasomal degradation of substrates but also regulates the autophagy pathway. In one type of macroautophagy, called selective autophagy, cargos are recruited to phagophore in a ubiquitin-dependent manner. Ubiquitin can target autophagy regulators for proteasomal degradation, control protein conformation or change interacting partners of these regulators. To understand the regulatory mechanisms of these degradation pathways, it is critical to dissect how the ubiquitin system contributes to them. Since enzymes are key regulators of ubiquitination, in this review, such enzymes in autophagy regulation are discussed, with specific focus on ubiquitin conjugating enzyme E2s, of which roles in autophagy are emerging.
