    basic FUNCTION
  • acting as a receptor potentially involved in both adhesion and signaling processes early after leucocyte activation
  • shows different features of expression and function in muscle cells compared to hematopoetic and tumor cells
  • is induced in multiple epithelial cancer lineages
  • plays an important role in tumor aggressiveness by binding its cellular ligand CD55
  • CD97 and CD55 both play important roles in tumor dedifferentiation, migration, invasiveness, and metastasis
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS immunity/defense , inflammation
    PATHWAY
    metabolism
    signaling signal transduction
    a component
  • CD97 heterodimerized and functionally synergized with LPAR1, a GPCR implicated in cancer progression
  • INTERACTION
    DNA
    RNA
    small molecule metal binding,
  • Ca2+
  • protein
  • binding to CD95, decay accelerating factor (DAF,CD55)
  • CD97 functioned to mediate invasion in prostate cancer cells, at least in part, by associating with lysophosphatidic acid receptor 1 (LPAR1)
  • CD97, present on peripheral myeloid cells, is a novel interacting partner for THY1 (is an interacting partner for CD97 on activated endothelial cells)
