LC3 versus GABARAP specialization

Evidence Snippets

This review synthesizes how LC3 versus GABARAP mediate distinct steps of autophagy (LC3 primarily governs cargo recruitment and phagophore expansion, whereas GABARAP drives autophagosome maturation, transport, and lysosomal fusion).

Astrocytes use autophagy for metabolic support and clearance of extracellular debris such as amyloid-beta plaques, and interface with neuronal autophagy through transcellular mechanisms.

Claim 2cell type functionsupports2026Source 1DOI PubMed

In neurons, presynaptic autophagy clears aging synaptic vesicles and organelles, while postsynaptic autophagy modulates receptor turnover and synaptic plasticity.

Claim 3disease relevancesupports2026Source 1DOI PubMed

Dysregulated autophagic flux and aggregate clearance contribute to neurodegenerative diseases including Alzheimer's and Parkinson's disease, and selective synaptic autophagy deficits are implicated in epilepsy and autism.
