WebOct 1, 2024 · Proliferating cells need to evaluate the environment to determine the optimal timing for cell cycle entry. However, how this is achieved is not well understood. Here, we show that, in budding yeast, the G1 inhibitor Whi5 is a key environmental indicator and plays a crucial role in coordinating cell growth and division.
