Research Interests
Our major interst in the molecular basis of signal transduction by retinal rod cells. These exquistely sensitive amplifiers can be triggered by a single photon. Furthermore, rods can adapt to 100,000-fold changes in background illumination. Their responses to stimuli are highly precise in amplitude and timing. The molecular assemblies mediating these processes are packaged in highly concentrated form in the outer segment, which can be readily isolated. We are exploring this gift of nature by biochemical, biophysical, molecular genetic and electrophysicological approaches to elucidate the molecular basis of visual excitation and adaption. Our curent research is focused on the feedback role of calcium ion in recovery and adaption. We have cloned and expressed recoverin and neurocalcin, two new calcium-sensors in the retina and brain. A related interest is the molecular mechanism of calcium spiking. We are exploring how cells generate and read calcium spikes.
