differential stress-induced degradation of YME1L (Montrer YME1L1 Protéines) and OMA1 as a mechanism for sensitively adapting mitochondrial inner membrane protease activity and function in response to distinct types of cellular insults.
The mitochondrial metalloprotease OMA1 was activated in a Bax (Montrer BAX Protéines)- and Bak (Montrer BAK1 Protéines)-dependent fashion.
Cleavage of the inner membrane fusion factor L-OPA1 (Montrer OPA1 Protéines) is prevented due to the failure to activate the inner membrane protease OMA1 in mitochondria that have a collapsed membrane potential.
OMA1 is cleaved to a short form (S-OMA1) by itself upon mitochondrial membrane depolarization; S-OMA1 is degraded quickly but could be stabilized by CCCP treatment or Prohibitin (Montrer PHB Protéines) knockdown in cells.
These findings demonstrate that (a) p53 (Montrer TP53 Protéines) and Oma1 mediate L-Opa1 (Montrer OPA1 Protéines) processing, (b) mitochondrial fragmentation is involved in CDDP-induced apoptosis in OVCA and CECA cells, and (c) dysregulated mitochondrial dynamics
OMA1 controls OPA1 (Montrer OPA1 Protéines) cleavage and function.
These results provide evidence for different substrate specificities of m-AAA (Montrer APP Protéines) proteases composed of different subunits and reveal a striking evolutionary switch of proteases involved in the proteolytic processing of dynamin (Montrer DNM1 Protéines)-like GTPases in mitochondria.
The m-AAA (Montrer AAAS Protéines) protease associated with neurodegeneration limits MCU (Montrer MCU Protéines) activity in mitochondria.
stress-induced OMA1 activation and guanosine triphosphatase OPA1 cleavage limit mitochondrial fusion and promote neuronal death
The IMQC protease Oma1 is required for the stability of the respiratory supercomplexes and thus balanced and tunable bioenergetic function.
OMA1-mediated OPA1 proteolysis plays an important role in the disruption of mitochondrial dynamics in ischemic acute kidney injury.
Constitutive OPA1 cleavage by YME1L (Montrer YME1L1 Protéines) and OMA1 at two distinct sites leads to the accumulation of both long and short forms of OPA1 and maintains mitochondrial fusion.
Stress-induced OMA1 activation and autocatalytic turnover regulate OPA1-dependent mitochondrial dynamics.
This study shows that OMA1 plays an essential role in the proteolytic inactivation of the dynamin (Montrer DNM1 Protéines)-related GTPase (Montrer RACGAP1 Protéines) OPA1 and describes its unexpected role in energy metabolism
OMA1 regulates OPA1 cleavage in the mitochondrial inner membrane.
Metalloprotease that is part of the quality control system in the inner membrane of mitochondria. Following stress conditions that induce loss of mitochondrial membrane potential, mediates cleavage of OPA1 at S1 position, leading to OPA1 inactivation and negative regulation of mitochondrial fusion. Its role in mitochondrial quality control is essential for regulating lipid metabolism as well as to maintain body temperature and energy expenditure under cold-stress conditions (By similarity).
