Rethinking Opsins [PDF]

Molecular Biology and Evolution, 2022
Abstract Opsins, the protein moieties of animal visual photo-pigments, have emerged as moonlighting proteins with diverse, light-dependent and -independent physiological functions. This raises the need to revise some basic assumptions concerning opsin expression, structure, classification, and evolution.

Unconventional Roles of Opsins [PDF]

Annual Review of Cell and Developmental Biology, 2017
Rhodopsin is the classical light sensor. Although rhodopsin has long been known to be important for image formation in the eye, the requirements for opsins in non–image formation and in extraocular light sensation were revealed much later. Most recent is the demonstration that an opsin in the fruit fly, Drosophila melanogaster, is expressed in ...

Opsins for vision restoration

Biochemical and Biophysical Research Communications, 2020
Optogenetics is a biological technique that combines the advantageous spatial-temporal resolution of optics and genetic cell targeting to control cellular activity with unprecedented precision. It has found vast applications both in neurosciences and therapy, particularly in view of its application to restore vision in blind patients.

Pineal Opsin: a Nonvisual Opsin Expressed in Chick Pineal

Science, 1995
Pineal opsin (P-opsin), an opsin from chick that is highly expressed in pineal but is not detectable in retina, was cloned by the polymerase chain reaction. It is likely that the P-opsin lineage diverged from the retinal opsins early in opsin evolution. The amino acid sequence of P-opsin is 42 to 46 percent identical to that of the retinal opsins.
