• Molecular Mechanisms of Vision Studies on
  theActivation of the Heterotrimeric G-protein
  Transducin
• The detection of light by retinal rod cells is
  dependent on regulated activation of transducin,
  a heterotrimeric guanine nucleotide binding
  protein, by the photoreceptor rhodopsin.
  Rhodopsin and transducin are a model system for
  the study of ubiquitous interactions between the
  large class of 7 transmembrane receptors (a major
  target for pharmaceutical agents) and their
  cognate intracellular G proteins. In this talk,
  studies on the molecular mechanism by which
  transducin is activated by rhodopsin will be
  presented.

Interference

• In a modern experiment (1989) with electrons, one
  can shoot one electron at the time or all at
  once. The final pattern is the same
