PHYSICAL PROPERTIES
STRUCTURE
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
    • mono polymer homomer , dimer
    HOMOLOGY
    Homologene
    FAMILY potassium channel family B,(SHAB) subfamily
    CATEGORY transport channel
    SUBCELLULAR LOCALIZATION     plasma membrane
    basic FUNCTION
  • mediating the voltage-dependent potassium ion permeability of excitable membranes
  • assuming opened or closed conformations in response to the voltage difference across the membrane
  • is a selective marker of parvalbumin (PV) neurons
