Discovery of a new family of key mitochondrial proteins for the function and viability of the brain
Date:5/9/2012

s forms part of the "wheel" machinery of mitochondria and regulates the localization of each cell on the basis of its energy requirements. "These genes would be like an extra control in cellular mitochondrial trafficking and they interact with the major proteins associated with the regulation of mitochondrial transport", explains Soriano.

Another striking characteristic of these new proteins is that they are found both in mitochondria, the function of which has already been described, and in the cell nucleus, where their function is unknown. "They may also be involved in the regulation of gene expression, a possibility that we are now studying". In addition to their potential involvement in brain pathologies, the researchers believe that these proteins may be related to metabolic diseases and cancer.
