External Ids 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 Channel, Voltage Gated Eag Related Subfamily H, Member 4) is a Protein Coding gene. Diseases associated with KCNH4 include campylobacteriosis. Among its related pathways are Signaling by FGFR and Signaling by FGFR. GO annotations related to this gene include voltage-gated potassium channel activity and phosphorelay sensor kinase activity. An important paralog of this gene is KCNH1.
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 pore-forming alpha-subunits contain a single pore-forming region and combine to form tetramers. Heteromeric channels can be formed within subfamilies e.g. KV1.1 with KV1.2 and KCNQ2 with KCNQ3.
