Flexible Protein Gate Controls Mitochondrial Access

Mitochondria rely on cristae, deep inner membrane folds, to produce energy. The MICOS protein complex sits at the narrow openings of these folds, serving as a critical molecular filter and structural stabilizer.

Recent simulations reveal that MICOS functions as a flexible gate. By controlling molecular access, it maintains the integrity of the mitochondrial architecture, a process vital for preventing severe conditions like neurodegenerative diseases and cancer.
