motifs/domains
  • six putative membrane-spanning domains
  • an hydrophobic pore including the P domain with the K+ channel signature, flanked by TM domains 5 and 6, sensitive to changes in membrane potential
  • a segment s4 is probably the voltage-sensor and characterized by a series of positively charged amino acids at every third position
  • a tail may be important in modulation of channel activity and/or targeting of the channel to specific subcellular compartments
  • HOMOLOGY
    interspecies homolog to murine Kv3.3
    homolog to Drosophila Shaw-related family
