TL;DR: The identification of a novel opsin family, tmt-opsin, that has a genomic structure characteristic of vertebratePhotopigments, an amino acid identity equivalent to the known photopigment opsins, and the essential residues required for photopIGment function is reported.

TL;DR: It is reported the first isolation and in vitro expression of a functional cone-like photopigment from the highly degenerate eye of a visually blind fossorial mammal, the blind mole rat (Spalax ehrenbergi), and it is shown that this photopIGment mediates the effects of light on circadian behavior in this species.

TL;DR: The isolation and characterisation of a novel opsin cDNA from the retina and pineal of the common carp is reported and lamprey P opsin should be reassigned to the VA opsin family based upon its level of amino acid identity, genomic structure with respect to the position of intron 2 and nucleotide phylogeny.

TL;DR: The data provide strong evidence that this long wavelength sensitive (LWS) cone opsin of Spalax is spectrally tuned to enhance photon capture in the red light environment of the eye and suggest that multiple photopigments mediate the effects of light on the mammalian circadian system.
