Identification
HMDB Protein ID CDBP04850
Secondary Accession Numbers Not Available
Name Potassium voltage-gated channel subfamily A member 3
Description Not Available
Synonyms
  1. HGK5
  2. HLK3
  3. HPCN3
  4. Voltage-gated K(+) channel HuKIII
  5. Voltage-gated potassium channel subunit Kv1.3
Gene Name KCNA3
Protein Type Transporter
Biological Properties
General Function Involved in protein binding
Specific Function Mediates the voltage-dependent potassium ion permeability of excitable membranes. Assuming opened or closed conformations in response to the voltage difference across the membrane, the protein forms a potassium-selective channel through which potassium ions may pass in accordance with their electrochemical gradient
