タンパク質の説明:
Can induce tyrosine phosphorylation of TIE2. Binds to TIE2 receptor and counteracts blood vessel maturation/stability mediated by angiopoietin-1. Its function may be context-dependent. In the absence of angiogenic inducers, such as VEGF, ANG2-mediated loosening of cell-matrix contacts may induce endothelial cell apoptosis with consequent vascular regression.

研究背景

機能:

Binds to TEK/TIE2, competing for the ANGPT1 binding site, and modulating ANGPT1 signaling. Can induce tyrosine phosphorylation of TEK/TIE2 in the absence of ANGPT1. In the absence of angiogenic inducers, such as VEGF, ANGPT2-mediated loosening of cell-matrix contacts may induce endothelial cell apoptosis with consequent vascular regression. In concert with VEGF, it may facilitate endothelial cell migration and proliferation, thus serving as a permissive angiogenic signal.

サブユニット構造:

Interacts with TEK/TIE2, competing for the same binding site as ANGPT1.

タンパク質ファミリー:

Application: IF/ICC    Species: human and mouse    Sample: glomerular cells

Figure 2 ANGPT2 protein expression in glomerular cells of human and mouse. A. Immunofluorescence staining of ANGPT2 in normal human glomeruli. Podocyte marker, SYNPO, was co-stained, thereby localizing ANGPT2 to podocytes and non-podocytes. B. Similar co-staining of ANGPT2 and SYNPO in mouse glomeruli showing ANGPT2 is present in both podocytes and non-podocytes in mice.

Application: WB    Species: Human    Sample: mesangial cells

Figure 10 pAKT was increased in ANGPT2-treated podocytes but downregulated in mesangial cells in culture. Podocytes and mesangial cells were treated with 500 ng/ml ANGPT2 for 24 h and subject to immnunoblotting. The results represent the data from three independent experiments and are expressed as mean ± SD. **P<0.01 vs. control.
