一般描述
研究领域：细胞凋亡。天青蛋白是一种质周蛋白，是同型四聚体。
应用
天青素可用于：
- 骨肉瘤细胞系的细胞毒性和细胞活力研究
- 相互作用研究中氮化硅悬臂的功能化
- 氧化硅和云母的金表面和绝缘的功能化氧化物表面的涂层
生化/生理作用
在细菌反硝化过程中，天青蛋白作为亚硝酸盐还原酶的电子供体。天青蛋白表现出抗癌活性，因为它阻碍了与癌症进展相关的各种独立信号通路。它与肿瘤抑制蛋白p53结合，诱导癌细胞凋亡或阻止癌细胞生长。天青蛋白通过降低VEGFR-2酪氨酸激酶的活性来抑制肿瘤生长，从而破坏血管生成。已经观察到它在人类乳腺癌细胞和人类黑色素瘤细胞中显示出细胞毒性。
天青素是铜氧还蛋白家族中的金属蛋白。它比正常细胞优先进入癌细胞并诱导细胞凋亡。Azurin 与 ephrinB2 结构相似，并且实际上结合了 ephrin 受体酪氨酸激酶 EphB2 来启动参与癌症发展的细胞信号传导。天青素抑制 EphB2 酪氨酸残基的自磷酸化，干扰上游细胞信号传导并有助于抑制癌细胞生长。

Azurin is a bacterial-derived cupredoxin, which is mainly involved in electron transport reactions. Interest in azurin protein has risen in recent years due to its anticancer activity and its possible applications in anticancer therapies. Nevertheless, the attention of the scientific

The resolution of multidimensional NMR spectra can be severely limited when regular sampling based on the Nyquist-Shannon theorem is used. The theorem binds the sampling rate with a bandwidth of a sampled signal and thus implicitly creates a dependence between
