  • June 1st: Peter Lénárt (EMBL Heidelberg) - "The same, only different: how does the cytoskeleton adapt to meiosis-specific functions?"
  • June 22nd: Joe Howard (Yale University) - "Microtubles, motors and morphogensis"
  • Sept. 7th: Johan Elf (Uppsala University) - "Probing intracellular kinetics at single molecule sensitivity"

Cas9-based DNA targeting is radically different from that of transcription factors. Cas9 can be programmed by a guide RNA to target any sequence, at the price of the increased time required to open cellular dsDNA to test for complementarity. We have studied how much time it takes to located a singel target sequence in a living cell using single molecule fluorescence microscopy. We also measure how long time the bound dCas9 stays at a target sequences and what implications this has for repression of a targeted gene.
