SUCLA2 encodes for the ADP-forming β-subunit (A-SUCL-β) of succinyl CoA ligase, an enzyme of the citric acid cycle. Mutations in SUCLA2 lead to a mitochondrial disorder associated with mitochondrial DNA depletion. This mitochondrial disorder manifests as neonatal encephalomyopathy exhibiting dystonia, deafness and pronounced lesions in the basal ganglia. Despite that a SUCLA2 gene defect results in distinct brain pathology, precise localization of the encoded protein has never been investigated. Here we show that the immunoreactivity of A-SUCL-β in the human cerebral cortex was present exclusively in neurons, identified by their morphology and visualized by double labelling with a fluorescent Nissl dye. The A-SUCL-β immunoreactivity co-localized >99% with that of the d-subunit of the mitochondrial F0-F1 ATP synthase. Specificity of the anti-A-SUCL-β antiserum was verified by the absence of labelling in fibroblasts from a patient with a complete deletion of SUCLA2. A-SUCL-β immunoreactivity was absent in glial cells, identified by antibodies directed against the glial markers GFAP and S100. Our work establishes that SUCLA2 is expressed exclusively in neurons in the human cerebral cortex. Therefore, all encephalopathic features of the disease emerging by mutations in this gene originate solely from the neuronal cell population.
