The selfish mitochondrion [PDF]
Mitochondria match ATP supply to fluctuations in cellular energy requirements. Cellular energy requirements are often signaled to mitochondria by increases in the cytoplasmic concentration of Ca2+ ions. These increases in Ca2+ reach the mitochondrial matrix to regulate the proteins, enzymes and transporters required for mitochondrial ATP synthesis ...

Quality control of the mitochondrion [PDF]
Mitochondria are essential organelles that execute and coordinate various metabolic processes in the cell. Mitochondrial dysfunction severely affects cell fitness and contributes to disease. Proper organellar function depends on the biogenesis and maintenance of mitochondria and its >1,000 proteins.

Protein translocation pathways of the mitochondrion [PDF]
The biogenesis of mitochondria depends on the coordinated import of precursor proteins from the cytosol coupled with the export of mitochondrially coded proteins from the matrix to the inner membrane. The mitochondria contain an elaborate network of protein translocases in the outer and inner membrane along with a battery of chaperones and processing ...

The return of the mitochondrion [PDF]
For a fresh-faced (well, apart from the beard) PhD graduate in 1989, mitochondrial bioenergetics might have seemed a strange choice of research path. Flushed with the general acceptance of the chemiosmotic theory, many felt that the area had passed its heyday. With the publication of its ‘bible’ (Bioenergetics, the definitive textbook by David Nicholls)

Is Myelin a Mitochondrion? [PDF]
It has been hypothesized that myelin acts like a mitochondrion, generating ATP across the membranes of its sheath. By calculating the proton motive force across the myelin membrane based on known values for the pH and membrane potential of the oligodendrocyte, we find that insufficient energy could be harvested from proton flow across the myelin ...

An anaerobic mitochondrion that produces hydrogen [PDF]
Hydrogenosomes are organelles that produce ATP and hydrogen, and are found in various unrelated eukaryotes, such as anaerobic flagellates, chytridiomycete fungi and ciliates. Although all of these organelles generate hydrogen, the hydrogenosomes from these organisms are structurally and metabolically quite different, just like mitochondria where large ...

On the InterAktion between Hexokinase and the Mitochondrion [PDF]
The protein kinase Akt is now well recognized as a potent inhibitor of apoptosis. Work published by Majewski et al. in the December 3rd issue of Molecular Cell indicates that a major pathway by which Akt suppresses cell death is by stimulating the translocation of hexokinase to the mitochondrion.
