Research Interests
We are interested in the universal mechanism of transmembrane signal transduction mediated by heterotrimeric G-proteins, which are responsible for the transmission of information about extracellular messengers such as hormones, neurotransmitters and sensory stimuli, including visual signals.

Our laboratory is working on questions of the molecular organization of the receptor-G-protein complex, the high-resolution picture of the receptor-G-protein interface, the mechanism of signal transfer from the receptor, and the roles of individual G-protein subunits, especially the G-protein beta-gamma subunit complex, in this dynamic process.

The phototransduction cascade in highly specialized sensory neurons, retinal photoreceptor cells, is the prototypical G-protein-mediated system. As alterations of function of this system due to mutations, age-related processes or drug interactions may lead to severe visual disorders, one of our goals is the dissection of the phototransduction mechanism for clinical and therapeutic applications.
