Definition / general
  • Binds to CD55 and G protein-coupled receptors
  • May be involved in cell adhesion and signaling processes early after leukocyte activation
  • May be involved in migration of neutrophils (J Immunol 2004;172:1125)
  • Highly expressed at sites of inflammation in skin, lung and rheumatoid arthritis
  • May contribute to angiogenesis associated with tumors (Blood 2005;105:2836)
  • Glycosylation causes CD97 to show two different epitopes, EGF and Stalk (Int J Cancer 2004;112:815)
