Fig. 4. VCX1 plays an important role in Ca²⁺ homeostasis in the pmc1 ${Delta}$ and pmr1 ${Delta}$ /pmc1 ${Delta}$ strains. (A) Total cellular Ca²⁺ levels measured with flame photometry. (B) Cytosolic free Ca²⁺ levels measured with an aequorin Ca²⁺ reporter system. The arrow represents the addition of 100 mM CaCl₂ (see Materials and Methods for further details).
