- aMotif required for recognition of rhodopsin by G-protein [87]
- bMotif interacting with NPxxY motif upon receptor activation for structural constraints [88]
- cGlutamic acid residues stabilizing the Schiff base bond
- dLysine residue forming Shiff base bond with retinal Motif providing structural constraints in response to photoisomerization during formation of the G protein-activating Meta II [89]
