Summary

KCNH4 (potassium voltage-gated channel subfamily H member 4, HGNC:6253) is a protein-coding gene on chromosome 17q21.2, encoding Voltage-gated delayed rectifier potassium channel KCNH4 (Q9UQ05). Pore-forming (alpha) subunit of a voltage-gated delayed rectifier.

Voltage-gated potassium (Kv) channels represent the most complex class of voltage-gated ion channels from both functional and structural standpoints. Their diverse functions include regulating neurotransmitter release, heart rate, insulin secretion, neuronal excitability, epithelial electrolyte transport, smooth muscle contraction, and cell volume. This gene encodes a member of the potassium channel, voltage-gated, subfamily H. This member is a pore-forming (alpha) subunit. The gene is brain-specific, and located in the neocortex and the striatum. It may be involved in cellular excitability of restricted neurons in the central nervous system.

All UniProt accessions (1): Q9UQ05

UniProt curated annotations — full annotation on UniProt →

Function. Pore-forming (alpha) subunit of a voltage-gated delayed rectifier. Activates at more negative voltages, exhibits fast prepulse-independent activation kinetics and deactivates much more slowly, but shows no inactivation.

Subunit / interactions. The potassium channel is probably composed of a homo- or heterotetrameric complex of pore-forming alpha subunits that can associate with modulating beta subunits.

Subcellular location. Membrane.

Tissue specificity. Detected only in brain, in particular in the telencephalon. Detected in putamen and caudate nucleus, and at lower levels in cerebral cortex, occipital and hippocampus.

Similarity. Belongs to the potassium channel family. H (Eag) (TC 1.A.1.20) subfamily. Kv12.3/KCNH4 sub-subfamily.
