一般說明

B834是BL21(1)的亲本菌株。这些缺乏蛋白酶的宿主是蛋氨酸营养缺陷型,允许用35S蛋氨酸和硒代蛋氨酸对目标蛋白质进行高比活性标记,用于结晶学(2)。

DE3表明宿主是λDE3的溶酶原,因此携带一个由lacUV5启动子控制的T7 RNA聚合酶基因的染色体拷贝。这些菌株适合于通过IPTG诱导从pET载体中克隆的靶基因生产蛋白质。
基因型:F-ompT hsdSB(rB- mB-) gal dcm met (DE3)

Transient receptor potential melastatin 2 (TRPM2) is a Ca2+ -permeable, nonselective cation channel involved in diverse physiological processes such as immune response, apoptosis, and body temperature sensing. TRPM2 is activated by ADP-ribose (ADPR) and 2'-deoxy-ADPR in a Ca2+ -dependent manner.

Key to CRISPR-Cas adaptive immunity is maintaining an ongoing record of invading nucleic acids, a process carried out by the Cas1-Cas2 complex that integrates short segments of foreign genetic material (spacers) into the CRISPR locus. It is hypothesized that Cas1

In flies, Centrosomin (Cnn) forms a phosphorylation-dependent scaffold that recruits proteins to the mitotic centrosome, but how Cnn assembles into a scaffold is unclear. We show that scaffold assembly requires conserved leucine zipper (LZ) and Cnn-motif 2 (CM2) domains that co-assemble
