Previous GeneCards Identifiers for KCNH4 Gene
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.

GeneCards Summary for KCNH4 Gene
KCNH4 (Potassium Voltage-Gated Channel Subfamily H Member 4) is a Protein Coding gene. Among its related pathways are Potassium Channels and Transmission across Chemical Synapses. GO annotations related to this gene include signal transducer activity and voltage-gated potassium channel activity. An important paralog of this gene is KCNH8.
UniProtKB/Swiss-Prot for KCNH4 Gene
Pore-forming (alpha) subunit of voltage-gated potassium channel. Elicits an outward current, but shows no inactivation. Channel properties may be modulated by cAMP and subunit assembly.
Voltage-gated potassium channels (KV) belong to the 6-TM family of potassium channel that also comprises the Ca2+-activated Slo (actually 7-TM) and the Ca2+-activated SK subfamilies. The alpha-subunits contain a single pore-forming region and combine to form tetramers.
