VISUAL PHOTOTRANSDUCTION PATHWAY (PW:0000962)

View Ontology Report

Description

Two types of photoreceptors in the vertebrate retina mediate the light response: the rods which mediate vision in dim light and the cones which mediate bright light and color vision. Both sense light with a visual pigment composed of vitamin A derived chromophore 11-cis retinal and a G-protein coupled receptor (GPCR) to which the chromophore is covalently bound. Humans have one rod and three cones for long, medium- and short-waves. Rods and cones differ in their morphology, details of signaling
