quence of PT pore opening. Every student of biochemistry is taught the importance A second model predicts a specific channel located of cytochrome c for oxidative phosphorylation in mitoin the outer membrane that allows release of cytochondria, where it assists with production of lifechrome c. Moreover, a good candidate was identified sustaining ATP by participating in electron transport. in Ba...

not known. Interestingly, although the founder specification programs act upon the fusion process, the converse does not seem to be true. If the ability of myoblasts to fuse is blocked (for example by mutations in dock180/mbc), then the founder cells still make tiny Manfred Frasch*‡ and Maria Leptin†‡ *Department of Biochemistry and Molecular Biology Mount Sinai School of Medicine One Gustave L...
