Summaries for KCNH1 Gene

Entrez Gene Summary for KCNH1 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 of a voltage-gated non-inactivating delayed rectifier potassium channel. It is activated at the onset of myoblast differentiation. The gene is highly expressed in brain and in myoblasts. Overexpression of the gene may confer a growth advantage to cancer cells and favor tumor cell proliferation. Alternative splicing of this gene results in two transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2008]

GeneCards Summary for KCNH1 Gene

KCNH1 (Potassium Voltage-Gated Channel Subfamily H Member 1) is a Protein Coding gene. Diseases associated with KCNH1 include Temple-Baraitser Syndrome and Zimmermann-Laband Syndrome 1. Among its related pathways are Potassium Channels and Transmission across Chemical Synapses. GO annotations related to this gene include signal transducer activity and ion channel activity. An important paralog of this gene is KCNH8.

UniProtKB/Swiss-Prot for KCNH1 Gene

  • Pore-forming (alpha) subunit of a voltage-gated delayed rectifier potassium channel (PubMed:22732247). Channel properties may be modulated by subunit assembly, but not by cyclic nucleotides (By similarity). Mediates IK(NI) current in myoblasts (PubMed:9738473). Involved in the regulation of cell proliferation and differentiation, in particular adipogenic and osteogenic differentiation in bone marrow-derived mesenchymal stem cells (MSCs) (PubMed:23881642).

Tocris Summary for KCNH1 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 alpha-subunits contain a single pore-forming region and combine to form tetramers.

KCNH1_HUMAN :
  • The segment S4 is probably the voltage-sensor and is characterized by a series of positively charged amino acids at every third position.
  • Belongs to the potassium channel family. H (Eag) (TC 1.A.1.20) subfamily. Kv10.1/KCNH1 sub-subfamily.
Domain:
  • The segment S4 is probably the voltage-sensor and is characterized by a series of positively charged amino acids at every third position.
  • The C-terminal region interacts with the cyclic nucleotide-binding domain and contributes to regulate channel gating.
  • The PAS domain interacts with the cyclic nucleotide-binding domain and contributes to regulate channel gating.
  • The cyclic nucleotide-binding domain lacks residues that are essential for nucleotide-binding and cannot bind cyclic nucleotides. Instead, residues from the C-terminal domain (the so-called intrinsic ligand) bind in the cavity that would be expected to bind cyclic nucleotides. Interaction with the C-terminal region hinders interaction with CALM and reduces the affinity for CALM.
  • Contains 1 cyclic nucleotide-binding domain.
  • Contains 1 PAC (PAS-associated C-terminal) domain.
  • Contains 1 PAS (PER-ARNT-SIM) domain.
Family:
  • Belongs to the potassium channel family. H (Eag) (TC 1.A.1.20) subfamily. Kv10.1/KCNH1 sub-subfamily.
