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。

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

Swi2/Snf2 ATPases remodel protein:DNA complexes in all of the fundamental chromosome-associated processes. The single-subunit remodeler Mot1 dissociates TATA box-binding protein (TBP):DNA complexes and provides a simple model for obtaining structural insights into the action of Swi2/Snf2 ATPases. Previously we reported

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

The dicistrovirus, Cricket paralysis virus (CrPV) encodes an RNA interference (RNAi) suppressor, 1A, which modulates viral virulence. Using the Drosophila model, we combined structural, biochemical, and virological approaches to elucidate the strategies by which CrPV-1A restricts RNAi immunity. The atomic
