CD105 (Endoglin)

CD105 (26-176 a.a.) or Endoglin or GP160 is a Type I transmembrane protein, which is highly expressed on human vascular endothelial cells. It exists as an O- and N-glycosylated homodimer. Up-regulation of endoglin expression has been demonstrated in tumor vasculature and proliferating cells, suggesting that it is a proliferation-associated endothelial cell marker. CD105 binds to TGFBeta1 and Beta3 with high affinity but not TGF-Beta2.
