Potassium voltage-gated channel subfamily A member 2 (also known as Potassium Voltage-Gated Channel A Member 2 , Shaker-Related Subfamily, Member 2 or Voltage-Gated Potassium Channel Protein Kv1.2, or KCNA2) is a member of the Kv family of potassium channels. Kv1.2 contains six membrane spanning domains and belongs to the delayer rectifier class of potassium channels. Kv2.1 mediates the voltage dependent potassium ion permeability of excitable membranes. Kv1.2 binds PDZ domains of DLG1, DLG2 and DLG4. Kv1.2 is found primarily in the brain (at the axon initial segment, axon preterminals and juxtaparanode domains), central nervous system, but also in the cardiovascular system. Kv2.1 has been implicated in epileptic encephalopathy, early infantile, and episodic ataxia, type 1.
