In a world first, a research team has shown it is possible to engineer a quantum mechanical process inside proteins, opening the door to a new class of quantum-enabled biological technologies.

Structure of the photoreceptor synaptic assembly of the extracellular matrix protein pikachurin with the orphan receptor GPR179 The structure of the orphan GPCR GPR179 bound to the extracellular matrix component pikachurin is solved.

What do you get when #NationalProteinDay and #NationalPokémonDay meet? Pikachurin. ⚡

A 2023 #ScienceSignaling study solved the structure of this extracellular protein that plays an essential role in vision.⁠
