MFF (Mitochondrial Fission Factor): MFF is a protein that plays a crucial role in mitochondrial dynamics, especially in mitochondrial fission. By recruiting dynamin-related protein 1 (Drp1) to the outer mitochondrial membrane, MFF facilitates mitochondrial division, 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 impair mitochondrial shape and function, disrupting cellular energy balance and contributing to disease.
