  • FunctionPore-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.
  • Tissue specificityHighly expressed throughout the brain. Expression is very low or absent in other tissues.
  • Sequence similaritiesBelongs to the potassium channel family. D (Shal) (TC 1.A.1.2) subfamily. Kv4.2/KCND2 sub-subfamily.
  • DomainThe segment S4 is probably the voltage-sensor and is characterized by a series of positively charged amino acids at every third position.
  • Post-translational
    Phosphorylated on serine and threonine residues.
  • Cellular localizationCell membrane. Cell projection > dendrite. Detected in dendrites in cultured hippocampal neurons. Association with KCNIP2 probably enhances cell surface expression.

Anti-Kv4.2 antibody images

  • ICC/IF image of ab66639 stained PC12 cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab66639, 1/1000 dilution) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

Thank you for your phone call. I hope that increasing the primary antibody concentration and adding a permeabilization step with Tween 20 will help to increase the observed signal. If not, please let me know and I will be happy to assist you further.
