Biochem/physiol Actions
5′-核苷酸酶 (nucleotidase) 又称 CD73，是一种能转化核苷-5′−单磷酸生成核苷，底物偏好 AMP。天然 5'-核苷酸酶是一种 GPI 锚定蛋白，其暴露量因缺氧而上调。5′-核苷酸酶在体内有许多功能 ，包括产生细胞外腺苷。
5′-核苷酸酶具有多种临床意义。在体外肿瘤血管生成和体内肿瘤免疫逃逸中，它是调控肿瘤细胞增殖、迁移和侵袭的关键分子。由于这一重要角色，该酶是癌症研究的潜在靶点。也参与细胞外核苷酸的补救，并在组织稳态的控制中起关键作用。
General description
5′-核苷酸酶是广泛存在于哺乳动物细胞中的胞外酶。有助于从 5′ 加速磷酸基的水解反应核苷酸，产生相应的核苷。

Changes in nicotinamide adenine dinucleotide (NAD+) levels that compromise mitochondrial function trigger release of DNA damaging reactive oxygen species. NAD+ levels also affect DNA repair capacity as NAD+ is a substrate for PARP-enzymes (mono/poly-ADP-ribosylation) and sirtuins (deacetylation). The ecto-5'-nucleotidase CD73
