製品の詳細

Angiopoeitin-1 (Ang-1) and Antiopoietin-2 (Ang2) are important for development of the endothelium, by regulating tyrosine phosphorylation of the membrane receptor Tie-2/Tek. Ang-1 binding to Tie-2/Tek causes phosphorylation of the receptor. Ang-2 competes for this binding, and thus blocks receptor phosphorylation. Ang-1 has potential fibrinogen-like domain at the carboxy terminus and coiled-coil regions in the amino terminus. Ang-1 is prominently expressed in the myocardium of atrium and ventricle, mesenchymal and smooth muscle cells surrounding most blood vessels, and lung. In the adult, ANG-1 is also expressed in the heart and liver. To our knowledge, this is the first time that an Ang antibody recognises a band above 55 kD. This antibody (and the ang-2 antibody, ab8452) give a band at 75 kD which resembles the original size, because these are soluble highly glycosylated proteins, which should run higher than the calculated molecular weight of 55 kD.

補足情報

This supplementary information is collated from multiple sources and compiled automatically.

Angiopoietin 1 also known as Ang1 or Angpt1 is a protein important to the vascular system with a molecular mass of around 70 kDa. It is expressed widely in endothelial cells and fibroblasts. Angiopoietin 1 functions mechanically to bind the Tie2 receptor triggering signaling pathways that regulate blood vessel maturation and stability. This interaction is important for the development and maintenance of the blood vessel network.
Biological function summary

Angiopoietin 1 supports the structural integrity of blood vessels by interacting with the Tie2 receptor as part of a signaling complex. It helps prevent vascular leak and promotes endothelial cell survival migration and adhesion. By playing such roles Angiopoietin 1 is fundamental for maintaining vascular homeostasis and facilitating proper blood flow throughout the body. It also influences the immune response by modulating endothelial functions.

Pathways

Angiopoietin 1's involvement is most notable within the PI3K/AKT pathway and the MAPK pathway which are important for signaling cell survival and growth. These pathways work closely with other proteins such as VEGF (Vascular Endothelial Growth Factor) in angiogenesis and vascular remodeling. Angiopoietin 1 interacts with its related pathways to ensure that blood vessels remain functional and adaptive to physiological changes.

Angiopoietin 1 plays significant roles in cardiovascular diseases like atherosclerosis and diabetic vascular complications. Its dysregulation can lead to abnormalities in vascular maintenance and repair. There is also an association between Angiopoietin 1 and proteins like VEGF in cancer as both have roles in tumor angiogenesis. Understanding Angiopoietin 1's function could provide insights into therapeutic strategies for these conditions.

ターゲットの情報

Binds and activates TEK/TIE2 receptor by inducing its dimerization and tyrosine phosphorylation. Plays an important role in the regulation of angiogenesis, endothelial cell survival, proliferation, migration, adhesion and cell spreading, reorganization of the actin cytoskeleton, but also maintenance of vascular quiescence. Required for normal angiogenesis and heart development during embryogenesis. After birth, activates or inhibits angiogenesis, depending on the context. Inhibits angiogenesis and promotes vascular stability in quiescent vessels, where endothelial cells have tight contacts. In quiescent vessels, ANGPT1 oligomers recruit TEK to cell-cell contacts, forming complexes with TEK molecules from adjoining cells, and this leads to preferential activation of phosphatidylinositol 3-kinase and the AKT1 signaling cascades. In migrating endothelial cells that lack cell-cell adhesions, ANGT1 recruits TEK to contacts with the extracellular matrix, leading to the formation of focal adhesion complexes, activation of PTK2/FAK and of the downstream kinases MAPK1/ERK2 and MAPK3/ERK1, and ultimately to the stimulation of sprouting angiogenesis. Mediates blood vessel maturation/stability. Implicated in endothelial developmental processes later and distinct from that of VEGF. Appears to play a crucial role in mediating reciprocal interactions between the endothelium and surrounding matrix and mesenchyme.
