Gene Name CNGB3
Protein Type Transporter
Biological Properties
General Function Involved in ion channel activity
Specific 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. 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 efficiency of the channel when coexpressed with CNGA3. Essential for the generation of light-evoked electrical responses in the red-, green- and blue sensitive cones
