Potassium voltage-gated channel, Shaw-related subfamily, member 3 also known as KCNC3 or K_v3.3 is a protein that in humans is encoded by the ''KCNC3''.

Function

The Shaker gene family of Drosophila encodes components of

voltage-gated potassium channel Voltage-gated potassium channels (VGKCs) are potassium channel, transmembrane channels specific for potassium and Voltage-gated ion channel, sensitive to voltage changes in the cell's membrane potential. During action potentials, they play a ...

s and comprises four subfamilies. Based on sequence similarity, this gene is similar to one of these subfamilies, namely the Shaw subfamily. The protein encoded by this gene belongs to the delayed rectifier class of channel proteins and is an integral membrane protein that mediates the voltage-dependent potassium ion permeability of excitable membranes.

Clinical significance

KCNC3 is associated with

spinocerebellar ataxia Spinocerebellar ataxia (SCA) is a progressive, degenerative, genetic disease with multiple types, each of which could be considered a neurological condition in its own right. An estimated 150,000 people in the United States have a diagnosis of ...
