Secondary Accession Numbers
  • 13470
Name Potassium channel subfamily T member 1
Synonyms
  1. KCa4.1
Gene Name KCNT1
Protein Type Unknown
Biological Properties
General Function Involved in calcium-activated potassium channel activity
Specific Function Outwardly rectifying potassium channel subunit that may co-assemble with other Slo-type channel subunits. Activated by high intracellular sodium or chloride levels. Activated upon stimulation of G-protein coupled receptors, such as CHRM1 and GRIA1. May be regulated by calcium in the absence of sodium ions (in vitro)
