Expressioni

Inductioni

Is repressed by light, since the transcript is synthesized in the dark, but upon 20 minutes of illumination, transcript levels fall below detectable limits. This light-repressed transcript is present only in dark-adapted cells. Is rapidly translated at the onset of illumination; in fact, is one of the first proteins to be synthesized upon illumination of dark-adapted cells. Repression of the transcript in the light requires protein synthesis, which suggests that a specific protein is directly involved in lrtA light repression.2 Publications
