Research Area: Cell Research
Conclusions: It is well known that actin plays an essential role in muscle cell contraction, and cellular functions like skeleton/structure-function, organelle trafficking and cell migration. The authors studied how NAA80, by acetylating actin’s N-terminus, acts as a natural brake in the cells. Single-cell identification and tracking of movement was performed with HoloMonitor, and single-cell analysis used to demonstrate the power of this mechanism.
