MFF (Mitochondrial Fission Factor): MFF is a protein that plays a crucial role in mitochondrial dynamics, especially in the process of mitochondrial fission. By recruiting dynamin-related protein 1 (Drp1) to the outer mitochondrial membrane, MFF aids in the division of mitochondria, which is vital for proper mitochondrial distribution, quality control, and energy metabolism. This process supports cell health, growth, and adaptation to metabolic demands. Dysregulation of MFF can disrupt mitochondrial shape and function, impacting cellular energy balance and contributing to disease.
