Target Background

Function
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.
Gene References into Functions
  1. mutations cause a gainoffunction of KV4.3/KChIP2encoded channels by increasing membrane protein expression and slowing channel inactivation. PMID: 26016905
  2. Mefloquine is a concentration-dependent Ito and hKv4.3 channel blocker. PMID: 26216464
  3. Altered Kv4.3 channel localization and/or functioning resulting from SCA19/22 mutations may lead to Purkinje cell loss, neurodegeneration and ataxia. PMID: 25854634
  4. the interaction of DPP10a, expressed in human atrium, with Kv4.3 channels generates a sustained current component of Ito, which may affect late repolarization phase of atrial action potentials. PMID: 25600224
  5. Kv4.3 K(+) channel is involved in heart hypertrophy/heart failure independently of its electric function.[review] PMID: 24762397

  9. findings indicate mutations in KCND3 are not a common cause of disease among rarer types of European cerebellar ataxia; however 2 variants were identified in the SCA cases: p.L450F and p.P614S; mutations in KCND3 can cause 2 allelic disorders, SCA19/22 and Brugada syndrome which may co-occur PMID: 23963749

  19. The "structurally minimal" isoform KChIP2d modulates recovery of K(v)4.3 N-terminal deletion mutant Delta2-39. PMID: 21422811
  20. our findings suggest that KChIP1 interacts with Kv4.3 in interneurons at the stratum lacunosum-moleculare/radiatum junction PMID: 21129448

  27. the two arginines in the cytosolic C-terminal domain of alpha-subunits of Kv4 subfamily strongly regulate the voltage dependence of channel activation, inactivation, and recovery PMID: 14645239
  28. Both Kv4.3 and KChIP2 may contribute to epicardial-endocardial gradients in the transient outward current in normal and failing hearts. PMID: 15498806
