CC -!- FUNCTION: Visual signal transduction is mediated by a G-protein coupled
CC cascade using cGMP as second messenger. This protein can be activated
CC by cGMP which leads to an opening of the cation channel and thereby
CC causing a depolarization of rod photoreceptors. Essential for the
CC generation of light-evoked electrical responses in the red-, green- and
CC blue sensitive cones (By similarity). Induced a flickering channel
CC gating, weakened the outward rectification in the presence of
CC extracellular calcium, increased sensitivity for L-cis diltiazem and
CC enhanced the cAMP efficacy of the channel when coexpressed with CNGA3.
CC {ECO:0000250, ECO:0000269|PubMed:10662822}.
CC -!- SUBUNIT: Tetramer formed of three CNGA3 and one CNGB3 modulatory
CC subunits. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Membrane; Multi-pass membrane protein.
CC -!- TISSUE SPECIFICITY: Small subset of retinal photoreceptor cells and
CC testis. {ECO:0000269|PubMed:10662822}.
CC -!- SIMILARITY: Belongs to the cyclic nucleotide-gated cation channel (TC
CC 1.A.1.5) family. CNGB3 subfamily. {ECO:0000305}.
