3,4-didehydroretinal binding
Binding to 3,4-didehydroretinal, a form of retinal that plays a role in the visual process in freshwater fish and some amphibians analogous to that of all-trans retinal in other vertebrates. 3,4-didehydro-11-cis-retinal combines with an opsin to form cyanopsin (cone) or porphyropsin (rod).
