It is involved in adaptation. In Drosophila, calcium ions come in through trp channels and a submicrovillar reticulum. Serines and threonines get phosphorylated near the C terminal inside the cell. Here is the molecule that transducin activates in the rod. Luminal and cytoplasmic faces are shown.
Black dots are different amino acids.
Two cysteines near the C terminus are palmitylated, and those fatty acids are embedded in the membrane. Inside lumen is like outside cell, so inside lumen. How does this differ from how the cyclic nucleotides affect channels in rods. Describe the function of this metabotropic glutamate receptor in the taste receptor.
