Biological Activity

Description

CD105/Endoglin Protein, Human (Trx-His) is an accessory receptor for transforming growth factor beta (TGF-β), and is expressed on endothelial cells.

Background

Endoglin (CD105) is an accessory receptor for transforming growth factor beta (TGF-β) and its expression is up-regulated in actively proliferating endothelial cells. Endoglin is co-expressed with β-glycan, another component of the TGF-βR complex, in the microvascular endothelium of normal tissue. Endoglin is an appropriate marker for tumor-related angiogenesis and neovascularization. The endothelial cells of neoplasms are more prolific than endothelial cells of normal tissue and thus they express elevated endoglin levels[1].
