蛋白名称:Human CDK7 & CCNH & MNAT1 Heterotrimer Protein
蛋白构建:A DNA sequence encoding the human CDK7 (P50613) (Ala 2-Phe 346) was fused with a polyhistidine tag at the N-terminus, constructed the plasmid 1; A DNA sequence encoding the human CCNH (P51946) (Tyr 2-Leu 323) was fused with a polyhistidine tag at the N-terminus, constructed the plasmid 2. A DNA sequence encoding the human MNAT1 (P51948) (Asp 2-Ser 309) was fused with a polyhistidine tag at the N-terminus, constructed the plasmid 3. The three plasmids were co-expressed and the heterotrimer was purified.
表达宿主:Baculovirus-Insect Cells
蛋白纯度:> 85 % as determined by SDS-PAGE
蛋白活性:The specific activity is >5 nmol/min/mg using MBP as substrate.
蛋白内毒素:< 1.0 EU per μg of the protein as determined by the LAL method
预测N端:His & His & His
蛋白分子量:The recombinant heterotrimer of human CDK7/CCNH/MNAT1 comprises 1032 (364 + 341 + 327) amino acids and has a calculated molecular mass of 118.8 (41.2 + 39.7 + 37.9) kDa. The apparent molecular mass of rh CDK7/CCNH/MNAT1 heterotrimer is approximately 25,38 & 44 kDa respectively in SDS-PAGE under reducing conditions.

越发火热的 CRISPR Screen 技术又发大文章,耶鲁大学 Cell 揭示在 CD8 T 细胞中筛选出免疫治疗新靶点!
的应用[3]图片来源:Trends Cancer上海市肿瘤研究所的覃文新研究员团队利用 CRISPR Screen 技术,通过高通量功能基因组学筛查揭示了 CDK7 可以作为肝癌的潜在治疗靶点 [4]。生物信息学分析显示 CDK7 在肝癌组织中显著高表达。使用 CDK7 抑制剂 THZ1 处理肝癌细胞株后,部分肝癌细胞株 CDK7 抑制剂非常敏感,部分细胞株则不敏感。为肝癌防治提供了新思路。在病毒与宿主互作研究领域基于 CRISPR Screen 技术的宿主全基因组 sgRNA 文库高通量筛选平台,可快速发现
