Mitochondrial Membrane Stabilization (MMS)

Target
MMS
Molecular classification
Multi-component system, Lipid-protein interaction network, Structural maintenance pathway
01

Overview

Mitochondrial membrane stabilization encompasses the processes and components responsible for maintaining the structural and functional integrity of the inner and outer mitochondrial membranes. This stability is critical for efficient energy production, regulation of cell death pathways, and overall cellular health. Key factors involved include the mitochondrial membrane potential (ΔΨm), protein complexes like OPA1 and the MICOS complex, and lipids such as cardiolipin. Disruptions in mitochondrial membrane stabilization can lead to a variety of diseases, making it a target for therapeutic intervention.
