Summary
KCNH6 (potassium voltage-gated channel subfamily H member 6, HGNC:18862) is a protein-coding gene on chromosome 17q23.3, encoding Voltage-gated inwardly rectifying potassium channel KCNH6 (Q9H252). Pore-forming (alpha) subunit of voltage-gated inwardly rectifying potassium channel.
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. Alternative splicing results in multiple transcript variants that encode different isoforms.

Voltage-gated inwardly rectifying potassium channel KCNH6 — Q9H252 (reviewed: Q9H252)

All UniProt accessions (2): Q9H252, J3KSC2
UniProt curated annotations — full annotation on UniProt →
Function. Pore-forming (alpha) subunit of voltage-gated inwardly rectifying potassium channel. Characterized by unusual gating kinetics by producing relatively small outward currents during membrane depolarization and large inward currents during subsequent repolarization which reflect a rapid inactivation during depolarization and quick recovery from inactivation but slow deactivation (closing) during repolarization. Activates even more slowly than KCNH2.
Subunit / interactions. The potassium channel is probably composed of a homo- or heterotetrameric complex of pore-forming alpha subunits that can associate only within their subfamily.
Subcellular location. Cell membrane.
Tissue specificity. Expressed in prolactin-secreting adenomas.
Domain organisation. The S4-S5 linker acts as a signal integrator where it both couples voltage-sensor domain (VSD) movement to pore opening and closure, as well as providing a binding site for other domains that regulate activation and/or deactivation of the channel.
Similarity. Belongs to the potassium channel family. H (Eag) (TC 1.A.1.20) subfamily. Kv11.2/KCNH6 sub-subfamily.
