Previous GeneCards Identifiers 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. Diseases associated with KCNG4 include Amelogenesis Imperfecta, Type Iiia and Fundus Dystrophy. Among its related pathways are Potassium Channels and Transmission across Chemical Synapses. Gene Ontology (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 Summary 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).
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.
