Researchers have found that a protein vital for cell health that has recently been associated with cancer and diabetes, can juggle its cellular to-do list—in effect having two alike protein parts split the workload. A key protein for most life forms—the TH enzyme (transhydrogenase)—works inside mitochondria. “Despite its importance, TH has been one of the least-studied mitochondrial...

While all living organisms inherit mitochondria from their mothers, the father’s mitochondria are destroyed at the time of fertilization. Special cellular vesicles that originate in female fruit flies’ egg actively seek out and destroy the father’s mitochondria, according to research conducted by Dr. Eli Arama and a team in the Weizmann Institute’s Molecular Genetics Department.
