A time lapse experiment of Saccharomyces cerevisiae expressing GFP-tagged WHI5. WHI5 is a repressor of G1 transcription that binds to SCB binding factor (SBF) at SCB target promoters in early G1; phosphorylation of Whi5p by the CDK, Cln3p/Cdc28p relieves repression and promoter binding by Whi5; periodically expressed in G1. These phase, gfp images are part of an image group that ranges from CIL:35860-35879. 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.
