Melanopsin is a member of the opsin family, and is more closely related to photopigments in invertebrate visual cells than to pigments in vertebrate visual (rod and cone) cells.

There has been talk of optogenetics for the blind, implanting opsins in vision cells and developing special glasses that shine light into them.

If all went as planned, mammalian neurons would then produce light - sensitive microbial opsins as if they were proteins of their own.

The opsin's electric signals would need to fire and shut down within milliseconds of the stimulus to communicate as quickly as neurons; Deisseroth doubted that the simple biology of algae required such speed.

Using multiple opsins as well as blue, yellow, and green light, he can experiment with various combinations of activation in hopes of eliminating symptoms of disease.

Deisseroth realized that even the first step of his plan — inserting the microbial opsin molecule into a mammalian neuron and getting the two to sync up — was a long shot.

The animal does so by using the same family of light - sensitive proteins called opsins found in its eyes — a process not previously described for cephalopods.

Once someone has figured out how to get opsins inside the brains of primates and humans — Zhang at MIT is working on the problem now — optogenetic therapies targeting the brain can begin.

The results drive home the antiquity of invertebrate and vertebrate photoreceptors and opsins.

The researchers inserted an opsin into interneurons, a type of inhibitory neuron, in the mutant mice's prefrontal cortex.

Reasoning that the female version of L - opsin might also do the trick for males, researchers from the University of Washington used a harmless virus to carry the pigment gene behind the monkeys» retinas.

Females of the species contain two types of the ultraviolet opsin gene (UVRh1 and UVRh2), while males lack UVRh1.

Opsins change shape in response to light and initiate a chain of chemical reactions, which are eventually converted into nerve impulses.

In one type of squirrel monkey, the males lack a visual pigment called L - opsin.

However, adds Provencio, it's questionable how much melanopsin can tell us about other species: The protein shares only 39 % of the genetic code of its closest known relative, an octopus opsin.

They found this opsin, called Jaws, in a type of single - celled marine organism called an archaeon (Ar - KEE - on).

Lots of bacteria, fungi, algae and plants have opsins too.

In the new paper, Roska and Busskamp tested the Jaws protein in the mouse retina and found that it more closely resembled the eye's natural opsins and offered a greater range of light sensitivity, making it potentially more useful for treating retinitis pigmentosa.

For example, Bonin explains, a study might test whether turning on two types of nerve cells — each with a different opsin — gives different results from switching on just one.

Your eye contains opsin (OP - sin), one of these proteins.

A key advantage to this opsin is that it could enable optogenetic studies of animals with larger brains, says Garret Stuber, an assistant professor of psychiatry and cell biology and physiology at the University of North Carolina at Chapel Hill.

Finding such opsins expands the types of research scientists can do.

Most of the natural opsins now used for optogenetics respond best to blue or green light.
