| 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. |

| Catalog # | C5999-05 |
| 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. Applications | Suitable for use in ELISA and Western Blot. Other applications not tested. |
| Recommended Dilution | Western Blot: 1-10ug/ml (ECL). |
| ELISA: 0.5-1ug/ml |
| Optimal dilutions to be determined by the researcher. |
