PDE5调节血管平滑肌收缩，并参与血小板中的NO-cGMP信号传导以控制聚集。 PDE5也可能参与大脑中cGMP信号传导的调节，并可能调节压力诱导的心脏肥大和纤维化。磷酸二酯酶（PDE）是一种用于破坏磷酸二酯键的酶。磷酸二酯酶5（PDE5）是治疗勃起功能障碍和肺性高血压治疗的分子靶标。PDE5可用于寻找新的PDE5抑制剂。PDE5特异性靶向一氧化氮（NO）激活产生的环磷酸鸟苷（cGMP）。PDE5调节心血管和其他组织中的cGMP信号传导。在基因水平上，PDE5以多种异构体形式表达，并经历磷酸化作为翻译后修饰，导致其激活。PDE5由于亚硝基化而通过泛素途径降解。

Phosphodiesterase 5 (PDE5) is one of the most well-studied phosphodiesterases (PDEs) that specifically targets cGMP typically generated by nitric oxide (NO)-mediated activation of the soluble guanylyl cyclase. Given the crucial role of cGMP generated through the activation of this cellular

Cyclic nucleotide phosphodiesterases (PDEs) are enzymes that regulate the cellular levels of the second messengers, cAMP and cGMP, by controlling their rates of degradation. There are 11 different PDE families, with each family typically having several different isoforms and splice
