A time lapse experiment of Saccharomyces cerevisiae expressing GFP-tagged SIC1. SIC1 is an inhibitor of Cdc28-Clb kinase complexes that controls G1/S phase transition, preventing premature S phase and ensuring genomic integrity; phosphorylation targets Sic1p for SCF(CDC4)-dependent turnover; functional homolog of mammalian Kip1 These phase, gfp images are part of an image group that ranges from CIL:35740-35759. Note that there are additional groups showing time series of other cell cycle regulation proteins by the same authors in the Library.
Time-lapse images were collected on a DeltaVision system (Olympus IX71) with 60x/1.42 NA objective at 5 minute intervals. Please see the microscopy section in the referenced manuscript for details for image analysis.
