HMDB Protein ID CDBP04852
Secondary Accession Numbers Not Available
Name Potassium voltage-gated channel subfamily KQT member 4
Description Not Available
Synonyms
  1. KQT-like 4
  2. Potassium channel subunit alpha KvLQT4
  3. Voltage-gated potassium channel subunit Kv7.4
Gene Name KCNQ4
Protein Type Transporter
Biological Properties
General Function Involved in ion channel activity
Specific Function Probably important in the regulation of neuronal excitability. May underlie a potassium current involved in regulating the excitability of sensory cells of the cochlea. KCNQ4 channels are blocked by linopirdin, XE991 and bepridil, whereas clofilium is without significant effect. Muscarinic agonist oxotremorine-M strongly suppress KCNQ4 current in CHO cells in which cloned KCNQ4 channels were coexpressed with M1 muscarinnic receptors
