37228 Q94523 SDHA_DROME Succinate dehydrogenase [ubiquinone] flavoprotein subunit, mitochondrial (EC 1.3.5.1) (Flavoprotein subunit of complex II) (FP) (Succinyl coenzyme A synthetase flavoprotein subunit) DISRUPTION PHENOTYPE Disruption of mitochondrial function has no effect on the initial stages of photoreceptor development (R cells develop normally, adopt the correct cell fates, innervate the appropriate synaptic partners, and assemble synapses normally). However, beginning around the time of eclosion, R cells degenerate, progressively losing expression of synaptic markers and undergoing extensive morphological changes. Synapse loss is caused by reactive oxygen species (ROS) production, not energy depletion, as photoreceptor ATP levels are normal. {ECO:0000269|PubMed:18599508}.
