Table 2 Summary of the cell-type-specific differences involving bioenergetics, relative expression of SDHs, SDHs-multiprotein assembly, and PTMs of SDHs observed under CAMKK2 deletion conditions in HEK293 and HepG2 cells

From: CAMKK2 regulates mitochondrial function by controlling succinate dehydrogenase expression, post-translational modification, megacomplex assembly, and activity in a cell-type-specific manner
