Mammalian mitochondria may contain up to 1,500 different proteins, and many of
them have neither been confidently identified nor characterized. In this study,
we demonstrated that C11orf83, which was lacking experimental characterization,
is a mitochondrial inner membrane protein facing the intermembrane space. This
protein is specifically associated with the bc1 complex of the electron transport
chain and involved in the early stages of its assembly by stabilizing the bc1
core complex. C11orf83 displays some overlapping functions with Cbp4p, a yeast
bc1 complex assembly factor. Therefore, we suggest that C11orf83, now called
UQCC3, is the functional human equivalent of Cbp4p. In addition, C11orf83
depletion in HeLa cells caused abnormal crista morphology, higher sensitivity to
apoptosis, a decreased ATP level due to impaired respiration and subtle, but
significant, changes in cardiolipin composition. We showed that C11orf83 binds to
cardiolipin by its ?-helices 2 and 3 and is involved in the stabilization of bc1
complex-containing supercomplexes, especially the III2/IV supercomplex. We also
demonstrated that the OMA1 metalloprotease cleaves C11orf83 in response to
mitochondrial depolarization, suggesting a role in the selection of cells with
damaged mitochondria for their subsequent elimination by apoptosis, as previously
described for OPA1.
