Origami B宿主菌株在trxB和gor中携带与原始Origami菌株相同的突变，只是它们来自BL21的lacZY突变体，可以通过调节IPTG的浓度来精确控制表达水平。因此Origami B菌株在一个菌株背景中结合了BL21、Tuner和Origami菌株的理想特征。trxB和gor的突变分别在卡那霉素和四环素上是可选择的；因此，这些菌株不能与只能用卡那霉素或四环素选择的质粒一起使用。这些菌株还包括BL21的lon和ompT缺陷，可增加蛋白质的稳定性。
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。

Origami B宿主菌株携带与原始Origami菌株相同的突变，不同之处在于它们源自BL21的lacZY突变体，可以使用IPTG精确控制表达水平。

RAGE, a druggable inflammatory receptor, is known to function as an oligomer but the exact oligomerization mechanism remains poorly understood. Previously we have shown that heparan sulfate (HS) plays an active role in RAGE oligomerization. To understand the physiological significance

Glutamate receptor-like channels (GLRs) play important roles in numerous plant physiological processes. GLRs are homologous to ionotropic glutamate receptors (iGluRs) that mediate neurotransmission in vertebrates. Here we determine crystal structures of Arabidopsis thaliana GLR3.2 ligand-binding domain (LBD) in complex with

Glutamate receptor-like channels (GLRs) play vital roles in various physiological processes in plants, such as wound response, stomatal aperture control, seed germination, root development, innate immune response, pollen tube growth, and morphogenesis. Despite the importance of GLRs, knowledge about their

Galectin-1 (G1) and galectin-3 (G3) are carbohydrate-binding proteins that can signal apoptosis in T cells. We recently reported that a synthetic tetramer with two G1 and two G3 domains ("G1/G3 Zipper") induces Jurkat T cell death more potently than G1.

When unfolded proteins accumulate in the endoplasmic reticulum (ER), the unfolded protein response (UPR) increases ER-protein-folding capacity to restore protein-folding homeostasis. Unfolded proteins activate UPR signaling across the ER membrane to the nucleus by promoting oligomerization of IRE1, a conserved transmembrane
