OMA1 (Overlapping Activity with M-AAA protease 1) is a mitochondrial metalloprotease critical for maintaining mitochondrial homeostasis. Belonging to the M48 metalloprotease family, it features a conserved HEXXH motif essential for zinc-dependent proteolytic activity. OMA1 is anchored to the inner mitochondrial membrane and regulates mitochondrial dynamics by processing proteins involved in membrane remodeling, cristae structure, and mitophagy. Its best-characterized substrate is OPA1. a GTPase governing mitochondrial fusion. Under stress conditions (e.g., membrane depolarization, oxidative stress), OMA1 becomes activated, cleaving OPA1 to promote mitochondrial fragmentation – a process linked to apoptosis and quality control.
Recombinant OMA1 protein is engineered for in vitro studies, typically expressed in bacterial (e.g., E. coli) or mammalian systems with purification tags. This allows researchers to analyze its enzymatic kinetics, substrate specificity, and interactions without mitochondrial isolation complexities. Structural studies often modify its transmembrane domains to enhance solubility while preserving catalytic domains. Research applications include modeling mitochondrial stress responses, screening OMA1 inhibitors/activators, and investigating its role in diseases like neurodegenerative disorders (Parkinson’s, Alzheimer’s), cardiomyopathy, and metabolic syndromes where OMA1 dysregulation contributes to mitochondrial dysfunction. Its dual role as stress sensor and effector makes it a potential therapeutic target for conditions involving excessive mitochondrial fragmentation.
