A 20aa Peptide sequence near C-terminus of rat CNG3.
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 a and b subunits. Several CNG a-subunits (CNG alpha 1-3) & beta subunits (subunit 2 or CNGb1-2 or CNG4-5) and numerous isoforms. a-subunit can form functional channel by themselves, whereas, 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.
CNG2 or OCNC1 (rat/mouse/rabbit 664 aa, bovine 663 aa) is primarily expressed in olfactory sensory neurons. It is ~80% homologous with CNG1. Unlike CNG1, CNG2 is activated both by cAMP and cGMP. Another cGMP-gated channel called CNG3 (mouse 537 aa, rat 611 aa, human, 694 aa, bovine 706 aa, chicken 645 aa) has been cloned from heart, kidney, testis, sperm, and taste buds. Deletion of CNG3 gene in mice leads of degeneration of cone photoreceptors.
仕様
Size：100ug
Source Antigen：Rat synthetic peptide
Grade：Highly Purified
Purity：Highly purified
Form：Supplied as a liquid in PBS, pH 7.2, 0.09% sodium azide
Specificity：85% conserved in mouse CNG3. No significant sequence homology is detected with other CNGs. The control peptide, because of small size (MW 2.33kD), is not suitable for Western. It should be used for ELISA and antibody blocking to confirm specificity of antibodies
