  • Title: An autonomous cell-cycle oscillator involved in the coordination of G1 events.
    Author: Roussel MR.
    Journal: Bioessays; 2000 Jan; 22(1):3-5. PubMed ID: 10649283.
    Abstract:
    In early embryonic development, the cell cycle is paced by a biochemical oscillator involving cyclins and cyclin-dependent kinases (cdks). Essentially the same machinery operates in all eukaryotic cells, although after the first few divisions various braking mechanisms (the so-called checkpoints) become significant. Haase and Reed have recently shown that yeast cells have a second, independent oscillator which coordinates some of the events of the G1 phase of the cell cycle.(1) Although the biochemical nature of this oscillator is not known,it seems unlikely to be a redundant cyclin/cdk system. BioEssays 22:3-5, 2000.
