Ubiquitination in the regulation of autophagy

Blog Article

Autophagy, an efficient and effective approach to clear rapidly damaged organelles, macromolecules, and other harmful cellular components, enables the recycling of nutrient materials here and supply of nutrients to maintain cellular homeostasis.Ubiquitination plays an important regulatory role in autophagy.This paper summarizes the most recent progress in ubiquitin modification in various stages of autophagy, including initiation, elongation, and termination.Moreover, this paper shows that ubiquitination is an important way through which selective autophagy achieves substrate specificity.

Furthermore, we note the distinction between monoubiquitination and polyubiquitination in the regulation of autophagy.Compared with monoubiquitination, polyubiquitination is a more common strategy to regulate the activity of the autophagy molecular machinery.In addition, the role of neflintw-r6mpw ubiquitination in the closure and fusion of autophagosomes warrants further study.This article not only clarifies the regulatory mechanism of autophagy but also contributes to a deeper understanding of the importance of ubiquitination modification.
