Angiopoietin-2 (Ang-2; also ANGPT2) is a secreted glycoprotein that plays a complex role in angiogenesis and inflammation. Under reducing conditions, secreted monomeric Ang-2 is 65-66 kDa in size. Under non‑reducing conditions, both natural and recombinant Ang-2 form 140 kDa dimers, 200 kDa trimers, and 250-300 kDa tetramers and pentamers. Ang-2 is widely expressed during development, but it is restricted postnatally to highly angiogenic tissues such as the placenta, ovaries, and uterus . It is particularly abundant in vascular endothelial cells (EC) where it is stored in intracellular Weibel-Palade bodies. Both Ang-2 and the related Angiopoietin-1 (Ang-1) are ligands for the receptor tyrosine kinase Tie-2. Ang-2 is required for postnatal vascular remodeling, and it cooperates with Ang-1 during lymphatic vessel development. It mediates the up‑regulation of ICAM‑1 and VCAM‑1 on EC, which facilitates the adhesion of leukocytes during inflammation. Ang-2 is up‑regulated in both the endothelium and tumor cells of several cancers as well as in ischemic tissue. Its direct interaction with Integrins promotes tumor cell invasion. Ang-2 also promotes the neuronal differentiation and migration of subventricular zone progenitor cells.
