一般描述

聚(ADP-核糖)聚合酶 1(PARP-1)与动脉粥样硬化期间的炎症反应有关。
聚(ADP-核糖)聚合酶 1(PARP1)属于 PARP 家族,在进化过程中高度保守。PARP1 基因位于人染色体的 1q42.12 上。

应用

PARP-1 人类已用于 GST-pull down 试验中,用于谷胱甘肽 S-转移酶(GST)或 GST-环 GMP-AMP 合酶(cGAS)(GST-cGAS)的免疫沉淀。它也已用于体外核糖基化测定。
PARP-1 是一种核酶,可从 NAD+ 合成 ADP-核糖聚合物,特异性结合 Zn2+ 和 DNA,并识别 DNA 中的单链断裂。PARP1 已用于研究中评估与 PARP1 基因多态性相关的种族和组织特异性癌症风险。它也已用于研究 PARP-1 抑制剂对潜在癌症治疗。

生化/生理作用

PARP-1 可通过被激活的 caspase-3 或 caspase-7 裂解成 24kDA 和 89kDA 片段而失活。这导致修复 DNA 损伤的能力下降和细胞凋亡增加。
PARP-1 是一种核酶,可从 NAD 合成 ADP-核糖聚合物,特异性结合 Zn2+ 和 DNA,并识别 DNA 中的单链断裂。它参与碱基切除修复(包括短补丁和长补丁),DNA 链断裂的重新连接,并在 p53 表达和激活中起作用。已报道了大鼠脑组织中大量的基底神经元 DNA 损伤和 PARP 活性。研究表明,PARP-1 是 HIV-1 整合到 DNA 中所必需的。如果 PARP-1 缺乏,则不会产生 HIV-1 感染。
聚(ADP-核糖)聚合酶 1(PARP1)对于 DNA 损伤检测和修复、染色质修饰、细胞分化、转录和凋亡细胞死亡等多种功能很重要。它还在精子发生中起主要作用。PARP1 基因的多态性与少精症有关,并导致男性不育。
