Opto-Kv1
Multi-Component SwitchOpto-Kv1 is a photoactivatable voltage-gated potassium channel generated by fusing the light-sensitive LOV domain from Vaucheria frigida Aureochrome 1 to the N-terminus of a Kv1 subunit. It enables acute light-dependent regulation of Kv1 channel expression/function, and the Opto-Kv1(V400D) variant can down-regulate Kv1 currents in a blue light-dependent manner.
