Hot or cold: it matters to us, but also to the dividing egg cell. Over a wide range of temperatures, the hotter it is, the faster the cell divisions go. However, too hot, or too cold, and the cycles stop. In this work, we set out to understand how the scaling of cell cycle duration with temperature originates in the protein interaction network that drives the cycle forward. This was a collaboration with the labs of Jim Ferrell and Qiong Yang. Find the preprint on biorxiv!
