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 Channel, Voltage Gated Modifier Subfamily G, Member 4) 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 delayed rectifier potassium channel activity. An important paralog of this gene is KCNB2.

UniProtKB/Swiss-Prot for KCNG4 Gene

  • Potassium channel subunit. Modulates channel activity by shifting the threshold and the half-maximal activation to more negative values

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 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.
