Vertebrate vision relies on two types of photoreceptors, rods and cones, which signal increments in light intensity with graded hyperpolarizations. Rods operate in the lower range of light intensities ...
MVP, a Methanococcus jannaschii voltage-gated potassium channel, was cloned and shown to operate in eukaryotic and prokaryotic cells. Like pacemaker channels, MVP opens on hyperpolarization using S4 ...
Fluorescence anisotropy determines the depolarisation of the fluorescence emission. The key reasons for depolarization include energy transfer to another molecule with a different orientation or ...
