Summaries for KCNG3 Gene

Entrez Gene Summary for KCNG3 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 is a gamma subunit functioning as a modulatory molecule. Alternative splicing results in two transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2008]

GeneCards Summary for KCNG3 Gene

KCNG3 (Potassium Channel, Voltage Gated Modifier Subfamily G, Member 3) 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 KCNG3 Gene

  • Potassium channel subunit. Modulates channel activity

Tocris Summary for KCNG3 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.
