Summaries for KCNG4 Gene

Entrez Gene Summary for KCNG4 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 G. This member functions as a modulatory subunit. The gene has strong expression in brain. Multiple alternatively spliced variants have been found in normal and cancerous tissues. [provided by RefSeq, Jul 2008]

GeneCards Summary for KCNG4 Gene

KCNG4 (Potassium Voltage-Gated Channel Modifier Subfamily G Member 4) is a Protein Coding gene. Among its related pathways are Potassium Channels and Dopamine-DARPP32 Feedback onto cAMP Pathway. GO annotations related to this gene include ion channel activity and delayed rectifier potassium channel activity. An important paralog of this gene is KCNG1.

UniProtKB/Swiss-Prot for KCNG4 Gene

  • Potassium channel subunit that does not form functional channels by itself. Can form functional heterotetrameric channels with KCNB1; modulates the delayed rectifier voltage-gated potassium channel activation and deactivation rates of KCNB1 (PubMed:19074135).

Tocris Summary for KCNG4 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.

UniProtKB/Swiss-Prot:

KCNG4_HUMAN :
  • The transmembrane segment S4 functions as voltage-sensor and is characterized by a series of positively charged amino acids at every third position. Channel opening and closing is effected by a conformation change that affects the position and orientation of the voltage-sensor paddle formed by S3 and S4 within the membrane. A transmembrane electric field that is positive inside would push the positively charged S4 segment outwards, thereby opening the pore, while a field that is negative inside would pull the S4 segment inwards and close the pore. Changes in the position and orientation of S4 are then transmitted to the activation gate formed by the inner helix bundle via the S4-S5 linker region.
  • Belongs to the potassium channel family. G (TC 1.A.1.2) subfamily. Kv6.4/KCNG4 sub-subfamily.
