β-arrestin functionally regulates the non-bleaching pigment parapinopsin in lamprey pineal. [PDF]
The light response of vertebrate visual cells is achieved by light-sensing proteins such as opsin-based pigments as well as signal transduction proteins, including visual arrestin.

New spectral templates for rhodopsin and porphyropsin visual pigments [PDF]
A four-parameter model of spectral sensitivity curves was developed. Empirical equations were designed for A1- and A2-based visual pigments with the main α-band maximum absorptions (λmax) from 350 nm, near the ultraviolet, up to 635 nm in the far-red ...

Camera Color Correction for Cultural Heritage Preservation Based on Clustered Data
Cultural heritage preservation is a crucial topic for our society. When dealing with fine art, color is a primary feature that encompasses much information related to the artwork’s conservation status and to the pigments’ composition.

Accelerated evolution of dim-light vision-related arrestin in deep-diving amniotes
Arrestins are key molecules involved in the signaling of light-sensation initiated by visual pigments in retinal photoreceptor cells. Vertebrate photoreceptor cells have two types of arrestins, rod arrestin, which is encoded by SAG and is expressed in ...

The Genetic and Evolutionary Drives behind Primate Color Vision
Primate color vision is based on two to three cone types in the retina, each expressing a different class of visual pigment, making them the only mammals that possess trichromacy.

The effect of elevated hydrostatic pressure on the spectral absorption of deep-sea fish visual pigments [PDF]
The effect of hydrostatic pressure (0.1-54 MPa, equivalent to pressures experienced by fish from the ocean's surface to depths of ca. 5400 m) on visual pigment absorption spectra was investigated for rod visual pigments extracted from the retinae of 12 ...
