摘要: Aims Muscle ring finger (MuRF) proteins have been implicated in the transmission of mechanical forces to nuclear cell signaling pathways through their association with sarcomere. We recently reported that MuRF1, but not MurF2, regulates pathologic cardiac hypertrophy vivo. This was surprising given MuRF1 and MuRF2 interact each other many same sarcomeric experimentally.
