Erik Svensson

We thank our postdoc Natalie Roberts for leading a stimulating lab-meeting today on #colour #vision and #opsin genes in damselflies and other insects for members of #SvenssonLab and #TsuboiLab.

In the evening some of the lab members went to Café Ariman in Lund and later to see the movie "The Apprentice" at #Kino in #Lund

If you too like #opsin evolution, check our new #bioinformatics tool #Matreex to visualize the evolution of complex gene families, illustrated by the evolution of vertebrate red-sensitive visual opsins biorxiv.org/content/10.1101/20 #SMBE2023

Marjorie Liénard: method to express invertebrate opsin proteins in vitro, allowing to show spectral shifts in opsins in butterflies, with notably 2 paralogs of LW providing differentiation in function between the dorsal and ventral parts of the eye pnas.org/doi/abs/10.1073/pnas. #SMBE2023 #opsin #GeneDuplication #paralog

Our favourite #Platynereis #opsin now in the mammalian brain as a new #optogenetic tool!

"Here we ... found that the Platynereis dumerilii ciliary opsin ... is an efficient, versatile, light-activated bistable GPCR that can suppress synaptic transmission in mammalian neurons with high temporal precision in-vivo "

#Matreex can be used for teaching, as here with the classical example of opsin evolution: notice the parallele loss of blue- and green-sensitive opsins in snakes and mammals, the duplications in frugivorous old-world primates, and the duplications and losses in fishes according to habitat. #opsin #MolecularEvolution

A step function #opsin with extreme light sensitivity has been developed that can be activated with an external light source #ReserachHighlight
