| Research Abstract |
Kv4.2, an A-type K+ channel, changed its subcellular localization from soma to the dendrites and synapses during synaptogenesis. In order to investigate the mechanisms of this regulation, we used EGFP-tagged-fusion channels. The fusion proteins were found mainly in ER when cDNA was transfected in culture cells. The Kv4.2 binding proteins, such as KChIP1, enhanced the surface expression of the channels by promoting translocation from ER to Golgi body.
