| 产品介绍 | background: Functions in nuclear protein import as nuclear transport receptor. Serves as receptor for nuclear localization signals (NLS) in cargo substrates. Is thought to mediate docking of the importin/substrate complex to the nuclear pore complex (NPC) through binding to nucleoporin and the complex is subsequently translocated through the pore by an energy requiring, Ran-dependent mechanism. At the nucleoplasmic side of the NPC, Ran binds to the importin, the importin/substrate complex dissociates and importin is re-exported from the nucleus to the cytoplasm where GTP hydrolysis releases Ran. The directionality of nuclear import is thought to be conferred by an asymmetric distribution of the GTP- and GDP-bound forms of Ran between the cytoplasm and nucleus (By similarity). Mediates the nuclear import of RPS3A. In vitro, mediates the nuclear import of human cytomegalovirus UL84 by recognizing a non-classical NLS.

Mediates the nuclear import of RPS3A. In vitro, mediates the nuclear import of human cytomegalovirus UL84 by recognizing a non-classical NLS. Subunit: Binds with high affinity to RPS3A. The binding is coupled to RanGTP cycles. Binds to human cytomegalovirus UL84. Found in a cytosolic complex with ASF1A, ASF1B, CDAN1 and histones H3.1 and H4. Subcellular Location: Cytoplasm (By similarity). Nucleus (By similarity). Similarity: Belongs to the importin beta family. Contains 6 HEAT repeats. Contains 1 importin N-terminal domain.

文献和实验物由于分子量大，在进行聚丙烯酰胺凝胶电泳时迁移较慢，而没有结合蛋白的探针则较快；孵育的样本在进行聚丙烯酰胺凝胶电泳并转膜后，蛋白-探针复合物会在膜靠前的位置形成一条带，说明有蛋白与目标探针发送互作。 二、实验操作步骤 1、实验前准备 （1）合理的实验方案 根据研究目的合理设计特异性探针实验组以及非特异性探针对照组，如有必要还可以添加特异性抗体组、特异性核酸竞争组等 （2）样本制备 可以选择提取样本的总蛋白、核蛋白或者使用纯化好的目的蛋白。对样本蛋白进行定量，实验中等量加入蛋白
凝胶迁移滞留试验法 EMSA是近年发展起来的研究核酸与蛋白质 相互作用简单、快速、敏感的方法，目前已经成为转录因子研究的经典方法。其基本原理是蛋白质可以与末端标记的核酸探针结合，电泳时这种复合物比无蛋白质结合的探针在凝胶中泳动的速度慢，即表现为相对滞后。该方法可用于检测DNA结合蛋白、RNA结合蛋白，并可通过加入特异性的抗体来检测特定的蛋白质，并可进行未知蛋白的鉴定。 EMSA基本原理示意图 核转
◆ Super-shift反应(含激活的目的转录因子的核蛋白＋标记探针＋目的转录因子的特异抗体). 4. 预电泳和电泳： 0.25X TBE在冰上120V 预电泳1小时; 务必换掉预电泳的缓冲液, 用新的0.25X TB低温下150V，电泳约60分钟。 注意横压电泳的时候注意电流的数字变化,记录开始电泳和电泳结束的电流数据的变化! 5. 电转运 在0.5X TBE中390mA电转移40分钟, 注意转运膜的选择, 有一种离子加强型的转运效果比较
