Potassium voltage-gated channel subfamily C member 3 or Kv3.3 potassium channel, is a member of the potassium channel, voltage-gated, shaker-related subfamily and the Shaw subfamily (the family includes 4 members Kv3.1-Kv3.4). Note that this protein has several splice variants and that antibody N375/67 recognizes both Kv3.3b and Kv3.3a. Kv3.3 is primarily expressed in brain. Kv3.3 is highly expressed in purkinje cells and deep cerebellar nuclei in the cerebellum. Kv3.3a is also expressed in brain, but not found in the cerebellum. Kv3.3 is a membrane protein that mediates the voltage-dependent potassium ion permeability of excitable membranes. Diseases associated with the gene for this protein (Kcnc3) include Spinocerebellar Ataxia 13 and Autosomal recessive ataxic cerebral palsy.
