The cyclic-nucleotide gated channel (CNG channel) of the rod outer segment of the retina (ROS) has its closed conformation stabilized by nicotine. Calcium and cGMP influence the Ki of the channel current to nicotine. Calcium lowers the Ki and cGMP increases it, giving a range of Ki between 10(-11) and 10(-8) M.
