BRCA1(乳腺癌1号基因,Breast Cancer 1)是一种重要的抑癌基因,属于BRCA基因家族,该家族还包括BRCA2。BRCA家族基因的共同特点是参与DNA损伤修复和维持基因组稳定性,尤其在双链DNA断裂的同源重组修复(HR)中起核心作用。BRCA1编码的蛋白质是一种多功能核蛋白,具有多个功能域,包括RING结构域(负责泛素化修饰)和BRCT结构域(参与蛋白质相互作用)。其主要生物学功能包括:1)DNA损伤修复,通过与RAD51等修复蛋白结合促进同源重组修复;2)细胞周期调控,在G2/M检查点发挥作用;3)转录调控,影响多种基因表达;4)染色质重塑。BRCA1主要作用位点是细胞核,尤其在DNA损伤位点聚集形成修复焦点。突变(如致病性截短突变)会导致蛋白质功能丧失,显著增加乳腺癌、卵巢癌、前列腺癌和胰腺癌等风险,这种癌症易感性被称为遗传性乳腺癌-卵巢癌综合征(HBOC)。BRCA1突变还可能导致对PARP抑制剂敏感,这是基于"合成致死"原理的靶向治疗策略。过表达BRCA1可能增强基因组稳定性但可能干扰正常细胞周期,而表达降低则会导致DNA修复缺陷、基因组不稳定性增加和肿瘤发生风险升高。BRCA1与多个信号通路相互作用,包括p53、ATM/ATR和Fanconi贫血通路,其功能异常会影响这些通路的活动。在临床应用中,BRCA1突变检测已成为遗传性癌症风险评估的重要指标,并指导预防性措施和治疗选择。需要注意的是,不同种群中BRCA1突变谱存在差异,某些突变(如Ashkenazi犹太人中的185delAG和5382insC)具有族群特异性高频特征。
