PHYSICAL PROPERTIES
STRUCTURE
motifs/domains
  • a signal peptide
  • an extracellular N terminal domain with three TNFR-Cys repeats
  • a single transmembrane domain
  • an intracellular domain with a C terminal DEATH domain
  • mono polymer trimer
    HOMOLOGY
    interspecies homolog to murine downless
    Homologene
    FAMILY
  • tumor necrosis factor receptor family
  • CATEGORY signaling , receptor
    SUBCELLULAR LOCALIZATION     plasma membrane
    text membrane protein type 1
    basic FUNCTION
  • involved in hair induction and in the process of ectodermal differentiation
  • activator of JNK, NFKB and cell caspase-independent cell death pathways
  • activating the NF-kappaB pathway together with its downstream adaptator EDARADD (Edar-associated death domain) for the development of hair follicles, teeth, exocrine glands and other ectodermal derivatives
  • major genetic determinant of Asian hair thickness
  • crucial role of the EDAR signaling in development of hair, teeth, and sweat gland
  • CELLULAR PROCESS cell life, differentiation
    cell life, cell death/apoptosis
    PHYSIOLOGICAL PROCESS development
    PATHWAY
    metabolism
    signaling
    EDAR and TNFSFR19 signalling pathways act redundantly to regulate initiation of hair follicle development (Pispa 2008)
    a component
  • involvement of the MAP3K7IP2/TRAF6/MAP3K7 signaling complex in the EDAR signal transduction pathway
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • binding EDA
  • binding to EDARADD by their DEATH domains
  • activating NFKB through IKBKG (NEMO)
  • interacting with TRAF family members
  • cell & other
    REGULATION
    activated by ED1during hair follicle morphogenesis
    induced by activin B6
