Characterization of the melanopsin gene (Opn4x) of diurnal and nocturnal snakes
BMC Evolutionary Biology, 2019 Background A number of non-visual responses to light in vertebrates, such as circadian rhythm control and pupillary light reflex, are mediated by melanopsins, G-protein coupled membrane receptors, conjugated to a retinal chromophore.

Melanopsin-driven light adaptation in mouse vision. [PDF]
, 2014 BACKGROUND: In bright light, mammals use a distinct photopigment (melanopsin) to measure irradiance for centrally mediated responses such as circadian entrainment.

Melanopsin (Opn4) is an oncogene in cutaneous melanoma
Communications Biology, 2022 AbstractThe search for new therapeutical targets for cutaneous melanoma and other cancers is an ongoing task. We expanded this knowledge by evaluating whether opsins, light- and thermo-sensing proteins, could display tumor-modulatory effects on melanoma cancer.

Cell Reports, 2019 Summary: Light influences various behaviors and physiological processes that occur outside of our conscious perception, including circadian photoentrainment, sleep, and even learning and mood.

Frontiers in Cellular Neuroscience, 2022 Retinal ganglion cells expressing the photopigment melanopsin are intrinsically photosensitive (ipRGCs). ipRGCs regulate subconscious non-image-forming behaviors such as circadian rhythms, pupil dilation, and light-mediated mood.

Mixed Palettes of Melanopsin Phototransduction [PDF]
Cell, 2018 Animal photoreceptors divide into two fundamental classes, ciliary and rhabdomeric. Jiang and colleagues demonstrate that this boundary is disregarded by the intrinsically photosensitive retinal ganglion cells of mammals. These neurons draw from phototransduction mechanisms of both classes, enriching the signals that they produce to drive a diversity ...

Melanopsin Tristability for Sustained and Broadband Phototransduction [PDF]
Neuron, 2015 Mammals rely upon three ocular photoreceptors to sense light: rods, cones, and intrinsically photosensitive retinal ganglion cells (ipRGCs). Rods and cones resolve details in the visual scene. Conversely, ipRGCs integrate over time and space, primarily to support "non-image" vision. The integrative mechanisms of ipRGCs are enigmatic, particularly since

Localization of melanopsin in the lamprey retina.
, 2014 Localization of melanopsin visualized by in situ hybridization with an antisense probe for melanopsin (A) and immunohistochemistry with an anti-melanopsin antibody (B) in the lamprey retina. Melanopsin expression is observed in the inner horizontal cells

Melanopsin contributions to irradiance coding in the thalamo-cortical visual system.
PLoS Biology, 2010 Photoreception in the mammalian retina is not restricted to rods and cones but extends to a subset of retinal ganglion cells expressing the photopigment melanopsin (mRGCs).
