Activity summary

Angiopoietin-2 also known as ANG2 or ANGPT2 is a glycoprotein with a molecular mass of approximately 70 kDa. It plays an important role in angiogenesis facilitating blood vessel remodeling and maturation. The protein is mainly expressed in endothelial cells where it functions by binding to the Tie2 receptor partially disrupting the Angiopoietin-Tie2 signaling axis. This disruption modulates vascular stability and permeability. The lyophilized form of the ANG-2 protein is often used in research for functional assays like ANG-2 ELISA to quantify its levels in various biological samples.

Biological function summary

Human angiogenesis processes are significantly affected by Angiopoietin-2 which serves as an antagonist to Angiopoietin-1 in regulating vascular dynamics. Although it does not form a stable complex by itself ANG2 activity is closely linked to its interactions with the Tie2 receptor modulating signal pathways that govern endothelial cell survival and permeability. Because of its dual role either stabilizing or destabilizing blood vessels under different conditions ANG2 serves as an important regulator during both normal physiological events and pathophysiological conditions.

Pathways

Angiopoietin-2 significantly contributes to the angiogenesis signaling network. It is deeply involved in the VEGF (Vascular Endothelial Growth Factor) pathway where ANG2 acts to balance VEGF activities in angiogenesis and vessel permeability. The interplay between Angiopoietin-2 and other proteins such as Angiopoietin-1 which stabilizes the vessels is vital for the precise regulation of blood vessel homeostasis during normal and disturbed conditions.

Associated diseases and disorders

Angiopoietin-2 has a prominent role in the pathology of diseases like cancer and diabetic retinopathy. In cancer excessive ANG2 expression may lead to increased tumor angiogenesis and metastasis making it a target for cancer therapies. In diabetic retinopathy elevated levels of ANG2 correlate with vascular leakage contributing to disease progression. The relationship between Angiopoietin-1 and Angiopoietin-2 in these conditions emphasizes their collective impact on vascular anomalies associated with these disorders.
