Summaries for KCNS1 Gene

Entrez Gene Summary for KCNS1 Gene

  • Voltage-gated potassium channels form the largest and most diversified class of ion channels and are present in both excitable and nonexcitable cells. Their main functions are associated with the regulation of the resting membrane potential and the control of the shape and frequency of action potentials. The alpha subunits are of 2 types: those that are functional by themselves and those that are electrically silent but capable of modulating the activity of specific functional alpha subunits. The protein encoded by this gene is not functional by itself but can form heteromultimers with member 1 and with member 2 (and possibly other members) of the Shab-related subfamily of potassium voltage-gated channel proteins. This gene belongs to the S subfamily of the potassium channel family. [provided by RefSeq, Jul 2008]

GeneCards Summary for KCNS1 Gene

KCNS1 (Potassium Voltage-Gated Channel Modifier Subfamily S Member 1) is a Protein Coding gene. Among its related pathways are Potassium Channels and Dopamine-DARPP32 Feedback onto cAMP Pathway. GO annotations related to this gene include ion channel activity and delayed rectifier potassium channel activity. An important paralog of this gene is KCNS2.

UniProtKB/Swiss-Prot for KCNS1 Gene

  • Potassium channel subunit that does not form functional channels by itself. Can form functional heterotetrameric channels with KCNB1 and KCNB2; modulates the delayed rectifier voltage-gated potassium channel activation and deactivation rates of KCNB1 and KCNB2 (PubMed:10484328).

Tocris Summary for KCNS1 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.

UniProtKB/Swiss-Prot:

KCNS1_HUMAN :
  • The transmembrane segment S4 functions as voltage-sensor and is characterized by a series of positively charged amino acids at every third position. Channel opening and closing is effected by a conformation change that affects the position and orientation of the voltage-sensor paddle formed by S3 and S4 within the membrane. A transmembrane electric field that is positive inside would push the positively charged S4 segment outwards, thereby opening the pore, while a field that is negative inside would pull the S4 segment inwards and close the pore. Changes in the position and orientation of S4 are then transmitted to the activation gate formed by the inner helix bundle via the S4-S5 linker region.
  • Belongs to the potassium channel family. S (TC 1.A.1.2) subfamily. Kv9.1/KCNS1 sub-subfamily.
