General annotation (Comments)

Function

Visual signal transduction is mediated by a G-protein coupled cascade using cGMP as second messenger. This protein can be activated by cGMP which leads to an opening of the cation channel and thereby causing a depolarization of rod photoreceptors. Essential for the generation of light-evoked electrical responses in the red-, green- and blue sensitive cones By similarity. Induced a flickering channel gating, weakened the outward rectification in the presence of extracellular calcium, increased sensitivity for L-cis diltiazem and enhanced the cAMP efficacy of the channel when coexpressed with CNGA3. Ref.1

Subunit structure

Heterooligomeric complex with CNGA3. Ref.1

Subcellular location

Membrane; Multi-pass membrane protein.

Tissue specificity

Small subset of retinal photorecptor cells and testis. Ref.1

Sequence similarities

Belongs to the cyclic nucleotide-gated cation channel (TC 1.A.1.5) family. CNGB3 subfamily. [View classification]
