Rosetta宿主菌株是BL21衍生物，旨在增强真核蛋白的表达，该蛋白含有在大肠杆菌中很少使用的密码子。这些菌株在兼容的氯霉素抗性质粒上为AGG、AGA、AUA、CUA、CCC、GGA密码子提供tRNA。因此，Rosetta菌株提供了“通用”翻译，否则该翻译受大肠杆菌密码子使用的限制。tRNA基因由其天然启动子驱动。在Rosetta（DE3）pLysS中，稀有tRNA基因存在于携带T7溶菌酶基因的相同质粒上。
DE3表明宿主是λDE3的溶原菌，因此在lacUV5启动子的控制下携带T7 RNA聚合酶基因的染色体拷贝。这样的菌株适用于通过用IPTG诱导从克隆在pET载体中的靶基因生产蛋白质。

The three-dimensional organization of chromosomes can have a profound impact on their replication and expression. The chromosomes of higher eukaryotes possess discrete compartments that are characterized by differing transcriptional activities. Contrastingly, most bacterial chromosomes have simpler organization with local domains

The correct localization of Hedgehog effectors to the tip of primary cilia is critical for proper signal transduction. The conserved non-motile kinesin Kif7 defines a "cilium-tip compartment" by localizing to the distal ends of axonemal microtubules. How Kif7 recognizes microtubule ends

The crystal structure of the β2-adrenergic receptor (β2AR) bound to the G protein adenylyl cyclase stimulatory G protein (Gs) captured the complex in a nucleotide-free state (β2AR-Gsempty). Unfortunately, the β2AR-Gsempty complex does not provide a clear explanation for G protein

Regulation of the outer kinetochore complex Ndc80 is essential to ensure correct kinetochore-microtubule attachments during mitosis. Here, we present a novel mechanism of regulation that is intrinsic to its structure; tight bending of the Ndc80 complex inhibits its microtubule binding.

DNA methylation and H3K9me are hallmarks of heterochromatin in plants and mammals, and are successfully maintained across generations. The biochemical and structural basis for this maintenance is poorly understood. The maintenance DNA methyltransferase from Zea mays, ZMET2, recognizes dimethylation of
