Cyclic nucleotide-gated channel alpha 1, also known as CNGA1, is a human gene encoding an ion channel protein.[5] Heterologously expressed CNGA1 can form a functional channel that is permeable to calcium[6]. In rod photoreceptors, however, CNGA1 forms a heterotetramer with CNGB1 in a 3:1 ratio[7][8][9]. The addition of the CNGB1 channel imparts altered properties including more rapid channel kinetics and greater cAMP-activated current[10]. When light hits rod photoreceptors, cGMP concentrations decrease causing rapid closure of CNGA1/B1 channels and, therefore, hyperpolarization of the membrane potential.
