    SUBCELLULAR LOCALIZATION     plasma membrane
    text
  • multi-pass membrane protein
  • basic FUNCTION
  • epithelial amiloride-sensitive sodium channel, non-voltage gated, controling the reabsorption of sodium in kidney, colon, lung and sweat glands
  • also playing a role in taste perception
  • candidate molecule for pH sensing in the gastrointestinal system
  • alters proteolytic channel activation and enhances base-line channel activity
  • undergoes dynamin-independent endocytosis
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS active transport

    a component
  • component of a heterotetramer including two SCNN1D, one SCNN1B and one SCNN1G
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • COMMD1 associate with SCNN1D and downregulate its activity
  • CNKSR3 physically interacts with SCNN1A, B, D, NEDD4L, and SGK1 and stimulates SCNN1A, SCNN1B, SCNN1D function in a PDZ domain-dependent, aldosterone-induced manner
