Abstract
The Monte Carlo method was used to model the diffusion behaviors of functionally important proteins of the phototransduction system in retinal rod outer segment disk membranes. The results expand our knowledge of the mechanisms of inactivation of the main phototransduction heterotrimeric GTP-binding protein transducin.
