Summaries for KCNA7 Gene

Entrez Gene Summary for KCNA7 Gene

  • Potassium 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. Four sequence-related potassium channel genes - shaker, shaw, shab, and shal - have been identified in Drosophila, and each has been shown to have human homolog(s). This gene encodes a member of the potassium channel, voltage-gated, shaker-related subfamily. This member contains six membrane-spanning domains with a shaker-type repeat in the fourth segment. The gene is expressed preferentially in skeletal muscle, heart and kidney. It is a candidate gene for inherited cardiac disorders. [provided by RefSeq, Jul 2008]

GeneCards Summary for KCNA7 Gene

KCNA7 (Potassium Voltage-Gated Channel Subfamily A Member 7) is a Protein Coding gene. Among its related pathways are Transmission across Chemical Synapses and Potassium Channels. GO annotations related to this gene include ion channel activity and delayed rectifier potassium channel activity. An important paralog of this gene is KCNA10.

UniProtKB/Swiss-Prot for KCNA7 Gene

  • Mediates the voltage-dependent potassium ion permeability of excitable membranes. Assuming opened or closed conformations in response to the voltage difference across the membrane, the protein forms a potassium-selective channel through which potassium ions may pass in accordance with their electrochemical gradient (By similarity).

Tocris Summary for KCNA7 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.
