Reciprocal Degradation of YME1L and OMA1 Adapts Mitochondrial Proteolytic Activity during Stress
Open accessAbstract
The mitochondrial inner membrane proteases YME1L and OMA1 are critical regulators of essential mitochondrial functions, including inner membrane proteostasis maintenance and mitochondrial dynamics. Here, we show that YME1L and OMA1 are reciprocally degraded in response to distinct types of cellular stress. OMA1 is degraded through a YME1L-dependent mechanism in response to toxic insults that depolarize the mitochondrial membrane. Alternatively, insults that depolarize mitochondria and deplete cellular ATP stabilize active OMA1 and promote YME1L degradation. We show that the differential degradation of YME1L and OMA1 alters their proteolytic processing of the dynamin-like GTPase OPA1, a critical regulator of mitochondrial inner membrane morphology, which influences the recovery of tubular mitochondria following membrane-depolarization-induced fragmentation. Our results reveal the differential stress-induced degradation of YME1L and OMA1 as a mechanism for sensitively adapting mitochondrial inner membrane protease activity and function in response to distinct types of cellular insults.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
