An analog to digital converter creates nuclear localization pulses in yeast calcium signaling [PDF]

, 2018
AbstractSeveral examples of transcription factors that show stochastic, unsynchronized pulses of nuclear localization have been described. Here we show that under constant calcium stress, nuclear localization pulses of the transcription factor Crz1 follow stochastic variations in cytoplasmic calcium concentration.
