The cyclic nucleotides cAMP and cGMP are implicated in signal transduction events such as the visual transduction, relaxation of smooth muscles, intestinal secretion of water and salt, reabsorption of Na+ and water in the distal tubule of the nephrons.
cAMP/cGMP activate Ca2+ -permeable ion channels called cyclic nucleotide-gated channels (CNG or CNC).
Activation of CNG leads to depolarization of the membrane voltage and to a concomitant increase of the cytosolic Ca2+.
CNG consists of two distinct subunits, designated alpha and beta subunits.
Several CNG a-subunits (CNG alpha 1-3) and b-subunits (subunit 2 or CNGb1-2 or CNG4-5) and numerous isoforms.
a-subunit can form functional channel by themselves.
b-subunits modulate the channel property of a-subunits.
CNG display intracellular N and C-termini, 6 transmembrane domains or segments (S1-S6).
The region between S5 and S6 contains the ion-conducting pore (P).
The cyclic nucleotide-binding region is found at the c-terminus.
Native functional CNG may exists as heteromultimer containing some combination of a and b subunits.
Bovine CNG1 was initially cloned and characterized from rod cells.
CNG1 (rat 683aa, mouse 684aa, human 686aa; also describes as OCNC1) is primarily expressed in outer segment of photoreceptor rod cells, and in a variety of tissues (kidney, eye, pineal gland, pituitary, adrenal, spleen, brain, heart, skeletal muscle and testis).
Human/mouse CNG1 exhibit ~88% sequence homology
