The multi-subunit mitochondrial contact site and cristae organizing system (MICOS) is a conserved protein complex of the inner mitochondrial membrane that is essential for maintenance of cristae architecture. The core subunit Mic10 forms large oligomers that build a scaffold and induce membrane curvature. The regulation of Mic10 oligomerization is poorly understood. We report that Mic26 exerts a destabilizing effect on Mic10 oligomers and thus functions in an antagonistic manner to the stabilizing subunit Mic27. The mitochondrial signature phospholipid cardiolipin shows a stabilizing function on Mic10 oligomers. Our findings indicate that the Mic10 core machinery of MICOS is regulated by several mechanisms, including interaction with cardiolipin and antagonistic actions of Mic26 and Mic27.
