Tiny little things

Frataxin is so very very small compared to me and compared to the galaxy I am the size of frataxin. While the precise role of human frataxin remains to be determined, the molecule appears to be involved in regulating the export and/or inport of mitochondrial Fe. These are the things that never cease to amaze me. Fifteen to twenty years ago no one realized that these tiny little bits existed. Theory is all that existed concerning frataxin, now it is put to practical uses and we will eventually determine the role it plays. Interesting. Maybe, someone will one day determine my role in the universe. Tee hee!
