Background: Endoglin/CD105

Endoglin (CD105) is a 90 kDa type I transmembrane glycoprotein of the zona pellucida (ZP) family of proteins (1‑3). Endoglin and betaglycan/T betaRIII are type III receptors for TGF beta superfamily ligands, sharing 71% aa identity in the transmembrane (TM) and cytoplasmic domains. Endoglin is highly expressed on proliferating vascular endothelial cells, chondrocytes, and syncytiotrophoblasts of term placenta, with lower amounts on hematopoietic, mesenchymal and neural crest stem cells, activated monocytes, and lymphoid and myeloid leukemic cells (2‑5). Human Endoglin cDNA encodes 658 amino acids (aa) including a 25 aa signal sequence, a 561 aa extracellular domain (ECD) with an orphan domain and a two-part ZP domain, a TM domain and a 47 aa cytoplasmic domain (1‑3). An isoform with a 14 aa cytoplasmic domain (S-endoglin) can oppose effects of long (L) Endoglin (6, 7). The human Endoglin ECD shares 65-72% aa identity with mouse, rat, bovine, porcine and canine Endoglin. Endoglin homodimers interact with TGF-beta 1 and TGF-beta 3 (but not TGF-beta 2), but only after binding T betaRII (8). Similarly, they interact with activin-A and BMP-7 via activin type IIA or B receptors, and with BMP-2 via BMPR-1A/ALK-3 or BMPR-1B/ALK-6 (9). BMP-9, however, is reported to bind Endoglin directly (10). Endoglin modifies ligand-induced signaling in multiple ways. For example, expression of Endoglin can inhibit TGF-beta 1 signals but enhance BMP7 signals in the same myoblast cell line (11). In endothelial cells, Endoglin inhibits T betaRI/ALK5, but enhances ALK1-mediated activation (12). Deletion of mouse Endoglin causes lethal vascular and cardiovascular defects, and human Endoglin haploinsufficiency can a cause the vascular disorder, hereditary hemorrhagic telangiectasia type I (13, 14). These abnormalities confirm the essential function of Endoglin in differentiation of smooth muscle, angiogenesis, and neovascularization (2‑4, 12‑14). In preeclampsia of pregnancy, high levels of proteolytically generated soluble Endoglin and VEGF R1 (sFLT1), along with low placental growth factor (PlGF), are pathogenic due to antiangiogenic activity (15).

FAQs for Human Endoglin/CD105 APC‑conjugated Antibody

Showing  1 - 2 of 2 FAQs Showing All

  • Q: I wonder if you have a CD105 or CD34 antibody suitable for IHC that is specific for human and do not bind mouse?

    A: We do not have any anti-human CD34 or CD105 antibodies that are confirmed to NOT detect the mouse protein. When we have tested an antibody and confirmed that it will not react with mouse samples, we will add Mu(-) to the datasheet, and unfortunately all of our CD105 and CD34 antibodies will either detect the mouse protein, or they have not been used in mouse samples before.

  • Q: We are interested in CD105 antibodies that could react with dog, please let me know which products in your catalog you would recommend.

    A: We do not currently carry any CD105 antibodies that have been validated for use in dog samples. However, if you are interested in testing any of our CD105 antibodies with dog samples you would be eligible for our Innovators Reward Program, in which you can get a discount voucher for the purchase price of the product. Please contact us at innovators@novusbio.com with any questions regarding this program.
