Transducin je tri komponentni guanin nukleotid vezujući protein (G protein), koji stimuliše spregu rodopsina i cGMP-fosfodiesteraze tokom vizuelnih impulsa. Transducin alfa podjedinice u štapićima i kupama oka su kodirane zasebnim genima. Ti geni kodiraju alfa podjedinice štapića. Alternativno splajsovanje tih gena rezultuje u dve transkriptne varijante.[2]
