Specific Aims 1. To develop strategies to
regulate gene expression using light as a
stimulus. 2. To use computational tools to
optimize the selected strategies.
Our approach To utilize defined molecular
systems involved in gene regulation. The
activity of the molecules involved should be
amenable to regulation by light-induced changes
in protein conformation.

Specific Aim 2 To use computational tools to
optimize the selected strategies
  • The LovTAP system
  • Desired Features
  • Increased lifetime of the light-activated
    protein
  • Enhanced affinity of the binding of the
    light-activated protein to the DNA

Experimental Design Insight from Molecular
Dynamics and Biochemical Modeling
12
Applications
  • Specific and temporal induction of gene
    transcription in mammalian cells
  • Coupling with gene recombination systems
