一般說明
哺乳动物细胞表达两种不同但高度同源的cullin-4蛋白：cullin-4A和cullin-4B。Cul4A和Cul4B组成E3连接酶。与Cul4A相反，Cul4B位于细胞核。
應用
兔抗-Cullin-4B抗体适用于以表达人Cullin-4B的HEK-293T细胞在0.7-1.5 μg/mL的工作浓度下进行蛋白质印迹实验。在一项证明了CUL4B E3泛素连接酶在靶向Jab1（Jun激活结构域结合蛋白）进行降解并在调节骨形态发生蛋白信号转导中起关键作用的研究中，该抗体被用于免疫印迹。
生化／生理作用
Cullin-4 （Cul4）蛋白是调节细胞周期、基因组稳定性和DNA复制的泛素E3连接酶的核心成分。Cul4B可作为E3连接酶参与选择泛素化的特异性靶标。它与损伤特异性DNA结合蛋白 DDB1 和DDB2（紫外损伤DNA）有关，并可作为Cul4B E3 连接酶的底物募集因子（substrate-recruiting factor）。Cul4B 可使多种目标蛋白泛素化，包括β-连环蛋白、细胞周期蛋白E、组蛋白H2A。该基因的突变与X连锁智力低下有关。
Cullin-4B可使DNA损伤结合蛋白1 (DDB1) 无需依赖DDB2即可转移进入细胞核。与cullin-4A (Cul4A) 不同，cullin-4B (Cul4B) 不能泛素化DDB2。
標靶描述
Cullin-4B可形成一种能够充当E3泛素化连接酶的复合体，并催化细胞中特异性蛋白底物的多泛素化。该蛋白可与环指蛋白发生互作，并对多种调节因子的蛋白裂解是必需的

Beta-catenin is the key transducer of Wingless-type MMTV integration site family member (Wnt) signalling, upregulation of which is the cause of cancer of the colon and other tissues. In the absence of Wnt signals, beta-catenin is targeted to ubiquitin-proteasome-mediated degradation.
