Secondary Accession Numbers
  • 13461
Name Kv channel-interacting protein 4
Synonyms
  1. A-type potassium channel modulatory protein 4
  2. Calsenilin-like protein
  3. KChIP4
  4. Potassium channel-interacting protein 4
Gene Name KCNIP4
Protein Type Unknown
Biological Properties
General Function Involved in calcium ion binding
Specific Function Regulatory subunit of Kv4/D (Shal)-type voltage-gated rapidly inactivating A-type potassium channels. Probably modulates channels density, inactivation kinetics and rate of recovery from inactivation in a calcium-dependent and isoform-specific manner. In vitro, modulates KCND2/Kv4.2 and KCND3/Kv4.3 currents
