ANGPT2（angiopoietin 2），癌症关联基因，基因ID：285，该基因编码的蛋白是血管生成素1（angiopoietin 1，ANGPT1）和内皮细胞TEK酪氨酸激酶（TIE-2，TEK）的拮抗剂编码蛋白破坏血管重塑能力，可能诱导内皮细胞凋亡。已经发现了三个编码三种不同亚型的转录变体[由RefSeq提供，2008年7月]The protein encoded by this gene is an antagonist of angiopoietin 1 (ANGPT1) and endothelial TEK tyrosine kinase (TIE-2， TEK). The encoded protein disrupts the vascular remodeling ability of ANGPT1 and may induce endothelial cell apoptosis. Three transcript variants encoding three different isoforms have been found for this gene. [provided by RefSeq， Jul 2008]。
