Fig. 7. Model showing how cellular Ca²⁺ uptake in yeast is coordinately regulated by two distinct mechanisms. The first mechanism is a CCE-like response that couples cellular Ca²⁺ uptake to Ca²⁺ store depletion in the ER/Golgi apparatus. The second mechanism couples cellular Ca²⁺ uptake to the level of Ca²⁺ in the extracellular environment.
