ATG4B is a cysteine protease also known as autophagin-1 with a molecular mass of approximately 45 kDa. It is involved in the autophagy process by cleaving ATG8 family proteins. This protease facilitates the lipidation of LC3 an essential component of the autophagosome membrane. You find ATG4B expressed in various tissues especially in the brain liver and muscle where it plays important roles in cellular maintenance.
Biological function summary
ATG4B functions in the cellular autophagic machinery cleaving the C-terminal of ATG8 proteins. This processing is necessary for the conjugation to phosphatidylethanolamine and integration into autophagosomes. ATG4B is part of a larger autophagic complex that also includes other critical proteins like ATG7 and ATG3 helping prepare ATG8 proteins for autophagosome creation.
Pathways
ATG4B participates in the autophagy pathway by refining the cargo processing mechanism. It interacts with the mTOR signaling pathway which influences cell survival and growth based on nutrient availability. The ATG4B enzyme is closely related to ATG7 in the pathway as both contribute to the maturation of autophagosomes.
ATG4B has significant links to cancer and neurodegenerative disorders. In cancer ATG4B activity affects tumor survival since cancer cells exploit autophagy for growth under stress conditions. In neurodegenerative diseases like Alzheimer's alterations in ATG4B activity disrupt cellular homeostasis. This disruption connects to proteins like LC3 which are pivotal in neuron survival and function.
