Summaries for KCNH7 Gene

Entrez Gene Summary for KCNH7 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. There are at least two alternatively spliced transcript variants derived from this gene and encoding distinct isoforms. [provided by RefSeq, Jul 2008]

GeneCards Summary for KCNH7 Gene

KCNH7 (Potassium Channel, Voltage Gated Eag Related Subfamily H, Member 7) is a Protein Coding gene. Among its related pathways are Transmission across Chemical Synapses and Dopamine-DARPP32 Feedback onto cAMP Pathway. GO annotations related to this gene include signal transducer activity and inward rectifier potassium channel activity. An important paralog of this gene is KCNH1.

UniProtKB/Swiss-Prot for KCNH7 Gene

  • Pore-forming (alpha) subunit of voltage-gated potassium channel. Channel properties may be modulated by cAMP and subunit assembly

Tocris Summary for KCNH7 Gene

  • 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.
