CC -!- FUNCTION: Subunit of the rod cyclic GMP-gated cation channel, which is
CC involved in the final stage of the phototransduction pathway. When
CC light hits rod photoreceptors, cGMP concentrations decrease causing
CC rapid closure of CNGA1/CNGB1 channels and, therefore, hyperpolarization
CC of the membrane potential. {ECO:0000250|UniProtKB:Q00194}.
CC -!- SUBUNIT: Forms a heterotetramer with CNGB1 in a 3:1 ratio. May also
CC form cyclic nucleotide-activated homotetrameric channels, that are
CC efficiently activated by saturating cGMP, but poorly activated by
CC saturating cAMP compared to the heterotetramer with CNGB1.
CC {ECO:0000250|UniProtKB:Q00194}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:Q00194};
CC Multi-pass membrane protein {ECO:0000250|UniProtKB:Q00194}.
CC -!- TISSUE SPECIFICITY: Rod cells in the retina and inner medulla of
CC kidney.
CC -!- DOMAIN: The C-terminal coiled-coil domain mediates homotrimerization of
CC CNGA subunits. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the cyclic nucleotide-gated cation channel (TC
CC 1.A.1.5) family. CNGA1 subfamily. {ECO:0000305}.
