WebPeripherin 2 (Prph2) is a photoreceptor-specific tetraspanin protein present in the outer segment (OS) rims of rod and cone photoreceptors. It shares many common features with other tetraspanins, including a large intradiscal loop which contains several cysteines. This loop enables Prph2 to associate with itself to form homo-oligomers or with its … WebVisual systems detect light by monitoring the effect of photoisomerization of a chromophore on the release of a neurotransmitter from sensory neurons, known as rod and cone photoreceptor cells in vertebrate retina. In all known visual systems, the chromophore is 11-cis-retinal complexed with a prote …

They do not mediate color vision, and have a low spatial acuity. Cones are active at higher light levels ( photopic vision ), are capable of color vision and are responsible for high spatial acuity. The central fovea is populated exclusively by cones. chargie by hillzy
