How protein networks stabilize muscle fibers: Same mechanism as for DNA
The same mechanism that stabilises the DNA in the cell nucleus is also important for the structure and function of vertebrate muscle cells. This has been established by RUB-researchers led by Prof. Dr. Wolfgang Linke (Institute ...
