UniProtKB description:  Membrane-bound large subunit (CybL) of the mitochondrial electron transport chain complex II, which together with the membrane-bound small subunit (CybS), anchor the catalytic subunits to the inner mitochondria membrane (PubMed:10743611, PubMed:12742584, PubMed:2843227, PubMed:8435436). During the free-living egg-larvae stages, which occur in an aerobic environment, complex II acts as a succinate dehydrogenase by transferring electrons from succinate to ubiquinone (PubMed:10743611, PubMed:12742584, PubMed:8435436). During the parasitic larvae and adult stages, which occur in an anaerobic environment, complex II acts as a fumarate reductase by transferring electrons from rhodoquinol to fumarate (PubMed:10743611, PubMed:12742584, PubMed:8435436).
