MFF (Mitochondrial Fission Factor): MFF is a protein that plays a key role in mitochondrial dynamics, particularly in the process of mitochondrial fission. By recruiting dynamin-related protein 1 (Drp1) to the mitochondrial outer membrane, MFF facilitates the division of mitochondria, which is essential 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, affecting cellular energy balance and contributing to disease.
