Ubiquinol-cytochrome c reductase complex assembly factor 3 is a protein that in humans is encoded by the UQCC3 gene.[5] Located in mitochondria, this protein is involved in the assembly of mitochondrial Complex III, stabilizing supercomplexes containing Complex III.[6] Mutations in the UQCC3 gene cause Complex III deficiency with symptoms of hypoglycemia, hypotonia, lactic acidosis, and developmental delays.[7] This protein plays an important role as an antiviral factor, bolstering the ability of cells to inhibit viral replication, independent of interferon production.[8] The UQCC3 protein can be cleaved by OMA1 metalloprotease during mitochondrial depolarization, targeting the cell for apoptosis. Depletion of this protein alters cardiolipin composition, causing cellular and mitochondrial defects.[6]
