"If actin is blocked, transcription can't begin," de Lanerolle said. The finding is published in the current issue of Nature Cell Biology and follows an earlier discovery by de Lanerolle and his ...

Actin, a protein with a well-known job in the cytoplasm and an active role in muscle contraction, moonlights in the nucleus. It's function there was not understood, but now scientists find that it ...

Research groups at the University of Helsinki uncovered how motor protein myosin, which is responsible for contraction of skeletal muscles, functions also in non-muscle cells to build contractile ...

During muscle development, nuclei travel from the centre of the myofibre to the periphery, a process defective in certain diseases. A new study reveals that this movement is due to centripetal forces ...
