Working with single-celled protozoa the researchers found that two proteins monitor and adjust the cell geometry to ensure successful cell division. These proteins congregate at the location of distortions and perform structural functions. As one of the researchers explained:
What we found is an exquisitely tuned mechanosensory system that keeps the cells shipshape so they can divide properly ... It's clear that the two [proteins] need each other to operate as a cellular mechanosensor.
It is yet another example of life's exquisite tuning.
