A time lapse experiment of Saccharomyces cerevisiae expressing GFP-tagged SWI5. SWI5 is a transcription factor that recruits the Mediator and Swi/Snf complexes; activates transcription of genes expressed at the M/G1 phase boundary and in G1 phase; is required for expression of the HO gene controlling mating type switching; and whose localization to the nucleus occurs during G1 and appears to be regulated by phosphorylation by Cdc28p kinase. These phase, gfp z-series images are part of an image group that ranges from CIL:39586-39590. 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.
