UCP3 Gene
Uncoupling Protein 3 (UCP3) is a gene involved in mitochondrial uncoupling that has been studied in relation to immune function, metabolism, and chronic illness. Variants in UCP3 may influence how the body responds to infection, inflammation, and long-term recovery.

What is the UCP3 gene?
UCP3 encodes uncoupling protein 3, a protein involved in mitochondrial uncoupling. It belongs to the Mitochondrial category and is part of the Mitochondrial Energy Production & PEM biological cluster. UCP3 is expressed predominantly in skeletal muscle and regulates mitochondrial proton leak and fatty acid metabolism.
Biological role and pathway
UCP3 is involved in the mitochondrial uncoupling 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.
UCP3 and Long COVID / ME-CFS research
UCP3 variants may influence skeletal muscle energy metabolism and fatigue susceptibility in post-exertional malaise associated with Long COVID.
