ATG10 (Autophagy Related 10 E3 Ligase) is an E3-like enzyme essential for the conjugation of ATG12 to ATG5, a critical step in autophagosome formation. The ATG10 enzyme facilitates the covalent attachment of ATG12 to ATG5, which then forms a complex with ATG16L1 to create the E3-like complex that drives LC3 lipidation. This ubiquitin-like conjugation system is fundamental to autophagy initiation and expansion of the isolation membrane.
In neurons, ATG10-mediated autophagy is crucial for synaptic plasticity, mitochondrial quality control, and clearance of misfolded proteins. Defects in ATG10 and the broader autophagy machinery contribute to neurodegenerative disease pathogenesis by impairing cellular clearance pathways. Reduced ATG10 expression has been observed in Alzheimer's disease models, associated with compromised autophagic flux and amyloid accumulation. Enhancing ATG10 function represents a potential therapeutic approach for neurodegenerative conditions.
ATG10 encodes an E2-like conjugating enzyme essential for autophagosome formation. ATG10 catalyzes the conjugation of ATG12 to ATG5, a critical step in the ATG12-ATG5-ATG16L1 complex formation that functions as an E3 ligase for LC3 lipidation. This ubiquitin-like conjugation system is essential for autophagosome biogenesis. ATG10 is widely expressed and plays a fundamental role in both selective and non-selective autophagy. It is important for cellular homeostasis, protein quality control, and stress adaptation.
Ubiquitous expression in most tissues including brain. Upregulated under starvation conditions and cellular stress.
