The rod outer segment is made up of stacked discs each containing many types of proteins, in
particular rhodopsin, a light - sensitive pigment.
One
particular focus in our work is structure, dynamics, and interactions of G - Protein Coupled Receptors (Wu, H.; et al. «Structure of a class C GPCR metabotropic glutamate receptor 1 bound to an allosteric modulator»; Science; 2014; 58 or Alexander, N.; et al. «Energetic analysis of the
rhodopsin - G - protein complex links the alpha5 helix to GDP release»; Nat Struct Mol Biol; 2014; 56).
