Summaries for KCND1 Gene

Entrez Gene Summary for KCND1 Gene

  • This gene encodes a multipass membrane protein that comprises the pore subunit of the voltage-gated A-type potassium channel, which functions in the repolarization of membrane action potentials. Activity of voltage-gated potassium channels is important in a number of physiological processes, among them the regulation of neurotransmitter release, heart rate, insulin secretion, and smooth muscle contraction. [provided by RefSeq, Aug 2013]

GeneCards Summary for KCND1 Gene

KCND1 (Potassium Channel, Voltage Gated Shal Related Subfamily D, Member 1) 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 voltage-gated potassium channel activity and delayed rectifier potassium channel activity. An important paralog of this gene is KCNA10.

UniProtKB/Swiss-Prot for KCND1 Gene

  • Pore-forming (alpha) subunit of voltage-gated rapidly inactivating A-type potassium channels. May contribute to I(To) current in heart and I(Sa) current in neurons. Channel properties are modulated by interactions with other alpha subunits and with regulatory subunits

Tocris Summary for KCND1 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.
