Biochemistry and physiology of zebrafish photoreceptors
This model system and its contribution to the understanding of photoreception with a focus on the cone visual transduction cascade are introduced.
The opsins of the vertebrate retina: insights from structural, biochemical, and evolutionary studies
In this review, the current understanding of the structure, function, biochemistry, and evolution of the opsins that make up the photopigments in the vertebrate retina will be reviewed.
Evolution of Visual and Non-visual Pigments
This Volume examines the enormous diversity of visual pigments and traces the evolution of these G protein coupled receptors in both invertebrates and vertebrates in the context of the visual and non-visual demands dictated by a species' ecological niche.
Physiological studies of the interaction between opsin and chromophore in rod and cone visual pigments.
Methods for substituting the native Chromophore with various chromophore analogs to investigate how specific parts of the chromophores affect the signaling properties of the visual pigment and the function of photoreceptors are described.
Molecular models of human visual pigments: insight into the atomic bases of spectral tuning
The objective of this work is to construct molecular models of human rhodopsin and opsins, for which three-dimensional structures are not available, to analyze the retinal environment and identify the similarities and differences that characterize the human visual pigments.
Structure of cone photoreceptors
Opsins and mammalian photoentrainment
Only when melanopsin and other candidates for OP479 have been functionally expressed, and shown to encode a photopigment that matches the action spectrum of OP479, can firm conclusions about the identity of the non-rod, non-cone ocular photoreceptor of mammals be made.
Human retinal circuitry and physiology
The relation between structure and function of the different retinal pathways is reviewed and their possible roles for visual perception are addressed.
An Alternative Pathway Mediates the Mouse and Human Cone Visual Cycle
Evolution of visual pigments and related molecules.
Cloned cDNAs encoding molecules involved in the phototransduction system of visual cells, such as phosphodiesterase, opsin kinase and arrestin, are cloned and phylogenetic trees show that these molecules are classified into two groups; one is expressed in cones and another in rods, suggesting that rods and cones contain homologous molecules with different amino acid sequences.
