PHYSICAL PROPERTIES
STRUCTURE
motifs/domains
  • intracellular N and C terminus
  • two putative (N and C terminus region) transmembrane segments (TM2)
  • a large extracellular loop with nine cysteine residues scattered into three rich domains
  • mono polymer homomer
    HOMOLOGY
    interspecies homolog to murine Accn1
    Homologene
    FAMILY
  • amiloride-sensitive sodium channels superfamily
  • degenerin family
  • CATEGORY tumor suppressor , transport channel
    SUBCELLULAR LOCALIZATION     plasma membrane
    text
  • colocalizing with ACCN3
  • lanceolate nerve endings that lie adjacent to and surround hair follicle
  • basic FUNCTION
  • neuronal amiloride-sensitive cation (non voltage-dependent) channel 1, also permeable to Na+, K+, LI+ required for normal touch sensation, involved in cell death
  • may play an important role in the pathogenesis of multiple sclerosis (Bernardinelli 2007)
  • distributed throughout the nervous system and potentially involved in mechanosensation, hearing, vision, and taste functions (Malysz 2008)
  • H(+)-gated amiloride-sensitive cation channel, potential glioma tumor suppressor gene (Vandepoele 2008)
  • CELLULAR PROCESS cell life, cell death/apoptosis
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling signal transduction
    synaptic transmission
    a component
  • may be a central component of a mechanosensory complex
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • variant 1 (ASIC2A) interacting with ACCN3 to form a protein-gated channel sensitive to gadolinium
  • through C- terminus interact with protein interacting with C kinase (PICK)1, which targets PKC to the plasma membrane (Bashari 2009)
  • cell & other
