    motifs/domains
  • 6 Ig-like C2-type (immunoglobulin-like) domains
  • a cytoplasmic tail, with a stretch of basic charged AAs that may act as binding sites for actin-linking ezrin-radixin-moesin (ERM) proteins
  • its cytoplasmic region contains potential calmodulin-dependent protein kinase phosphorylation sites and protein kinase C phosphorylation sites

    text colocalized with ERM proteins at microspikes and microvilli of adherent cells and at the cellular uropod in polarized migrating leukocytes
    basic FUNCTION
  • prostaglandin F2 alpha receptor (FP), negative receptor
  • inhibiting the binding of prostaglandin F2-alpha (PGF2- alpha) to its specific FP receptor
  • through their direct interaction with ERM proteins, act as linkers to connect tetraspanin-associated microdomains to actin cytoskeleton regulating cell motility and polarity
  • self-associates independently from its association with tetraspanins, and tetraspanins can play a role on PDGFRN oligomerization status
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    a component
  • IFITM5 forms a complex with FKBP11-CD81-PTGFRN
  • major component of the tetraspanin web, a network of molecular interactions in the plasma membrane, in which it specifically associates with tetraspanins CD9 and CD81
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • direct partner of tetraspanins CD9 (Tspan29) and CD81 (Tspan28)
  • CD81 associated with PTGFRN
