文献有引用:

背景:
半胱氨酸蛋白酶家族的caspase家族在细胞凋亡中起着关键的作用。半胱氨酸天冬氨酸蛋白酶3是胱天蛋白酶家族成员中最广泛研究的凋亡蛋白。Caspase 3被合成为非活性前体酶,该酶在通过自身蛋白酶水解和/或由其它上游蛋白酶(例如Caspase 8, 9和10)裂解的细胞中进行处理。Caspase 3的处理形式由大(17kDa)和小(12kDa)亚基组成,它们共同形成活性酶。在ASP28 Ser29和ASP175 Ser176中裂解Caspase 3。活性Caspase 3蛋白水解裂解并激活其他胱天冬酶(例如胱天蛋白酶6, 7和9),以及细胞中的相关靶(例如PARP和DFF)。该基因的选择性剪接导致两个转录变体,编码相同的蛋白质。在免疫组织化学研究中,半胱氨酸天冬氨酸蛋白酶3表达已被广泛存在,但不存在于所有细胞类型中(例如,通常在皮肤上皮细胞、肾近端小管和集合管中报道)。Caspase 3水平的差异已被报道在短寿命性质的细胞(如生发中心B细胞)和长寿命的细胞(如地幔B细胞)中。Caspase 3是主要的半胱氨酸蛋白酶,参与了淀粉样蛋白β4A前体蛋白的裂解,这与阿尔茨海默病的神经元死亡有关。
与Caspase-3亚基p17和前体反应。

功能:
参与激活细胞凋亡的半胱氨酸天冬氨酸酶级联反应。在凋亡开始时,它在216’ASP-γ-GLY-217’键上裂解聚(ADP-核糖)聚合酶(PARP)。裂解和激活甾醇调节元件结合蛋白(SREBPS)之间的基本螺旋-环-螺旋-亮氨酸拉链域和膜附着域。裂解并激活cas-6,- 7和- 9。参与了亨廷顿的解理。通过RET切割触发交感神经元的细胞粘附。

Subunit:
异四聚体,由两个反平行排列的异源二聚体组成,每一个由17 kDa(p17)和12 kDa(p12)亚基构成。与BiC6/布鲁斯互动。

亚细胞定位:
细胞质。

组织特异性:
高表达于肺、脾、心、肝、肾。脑和骨骼肌中等水平,睾丸低。在许多细胞系中也发现,免疫系统中细胞的最高表达。

翻译后修饰:
颗粒酶B、半胱氨酸天冬氨酸蛋白酶6、半胱氨酸天冬氨酸蛋白酶8和半胱氨酸天冬氨酸蛋白酶10裂解产生两个活性亚基。前肽的额外加工很可能是由于活化蛋白酶的自催化活性。Caspase-7蛋白酶亚基和Caspase-3大亚基之间也存在活性异二聚体,反之亦然。
S-亚硝基化在其催化位点半胱氨酸在未刺激的人细胞系中,并且在激活Fas凋亡途径时脱硝,与细胞内caspase活性的增加相关。因此,Fas不仅激活Caspase-3的活性,而且还通过刺激其活性部位巯基的脱氮作用来激活胱天蛋白酶酶原。

相似性:
属于肽酶C14A家族。

重要注意事项:
所提供的产品仅用于研究用途,不用于人体、治疗或诊断应用。
Caspase3广泛分布于各种不同类型的细胞中,是Caspase家族中最重要的凋亡执行者之一,激活的Caspase-3能使许多与细胞结构、细胞周期及DNA修复等相关蛋白或激酶失活,从而使细胞凋亡.
