CRAC channels drive digital activation and provide analog control and synergy to Ca(2+)-dependent gene regulation.
Ca(2+)-dependent gene expression is critical for cell growth, proliferation, plasticity, and adaptation [1-3]. Because a common mechanism in vertebrates linking cytoplasmic Ca(2+) signals with activation of protein synthesis involves the nuclear factor of activated T cells (NFAT) family of transcription factors [4, 5], we have quantified protein expression in single cells following physiological Ca(2+) signals by using NFAT-driven expression of a genetically encoded fluorescent protein. We fi...Expand abstract
