ATG5 Gene

Autophagy Related 5 (ATG5) is a gene involved in autophagosome membrane elongation that has been studied in relation to immune function, metabolism, and chronic illness. Variants in ATG5 may influence how the body responds to infection, inflammation, and long-term recovery.

What is the ATG5 gene?

ATG5 encodes autophagy related 5, a protein involved in autophagosome membrane elongation. It belongs to the Autophagy category and is part of the Mitochondrial Energy Production & PEM biological cluster. ATG5 forms the ATG12-ATG5-ATG16L1 E3-like complex essential for autophagosome membrane elongation.

Biological role and pathway

ATG5 is involved in the autophagosome membrane elongation pathway, which plays a central role in regulating physiological processes relevant to immune defence, cellular energy, and systemic homeostasis. Genes within the Mitochondrial Energy Production & PEM cluster work together to maintain balanced function across interconnected biological systems.

Variants in genes within this pathway may influence an individual's predisposition to altered function in these systems — particularly under conditions of physiological stress such as viral infection or prolonged illness.

ATG5 and Long COVID / ME-CFS research

ATG5-mediated autophagosome formation is essential for xenophagy (viral autophagy); variants may impair SARS-CoV-2 clearance and contribute to persistent viral reservoirs in Long COVID.
