New import pathway into the cell's powerhouses

Researchers have used artificial membranes to show how a particular protein reaches the mitochondria. Mitochondria serve as the powerhouses of the cell, converting the energy stored in foods into a form cells can use. When this important task fails, it can result in numerous diseases, particularly those affecting organs with a high energy consumption like the brain or the heart. The research team has discovered a new import pathway proteins use to reach the mitochondria.
