Pigment Dispersing Factor: Transcriptional Regulation And Its Role In Metabolism In Drosophila Melanogaster, Sudershana Nair

Doctoral Dissertations

Almost all living organisms have circadian clocks coordinating physiology and behavior, and an innate molecular clock drives rhythmic changes by integrating environmental and metabolic stimuli to generate 24 hour timing. Drosophila melanogaster has proved to be an excellent model organism with a well-characterized circadian clock and the neural circuits underlying clock have been intensely investigated. The neuropeptide pigment-dispersing factor (PDF) plays an essential role in maintaining circadian rhythmicity and synchronizes circadian clock neurons. However, the regulation of Pdf has been a black box with no known protein identified that directly regulates it, and its role in metabolism hasn’t been looked …
