General description

This plasmid is designed to express tagged proteins in E. coli. The plasmid contains a constitutive promoter (OXB20) derived from the region upstream of the E. coli RecA gene. It does not require induction or any additional components for activity. It is the strongest of the bacterial promoters that we provide and this high level of expression can cause expression problems with some proteins with poor solubility. For this reason we sell a range of bacterial promoters with different expression levels (OXB1(low)>OXB20(high)) that can be provided with the peptide tags in this plasmid on request.

About the Peptide Tag:This plasmid contains an n-terminal Deca-Histidine (10His) affinity tag that can be fused to a gene of interest to allow protein detection and/or purification. The sequence of the tag is: HHHHHHHHHH.

About the Cleavage Tag:This plasmid also encodes a protease cleavage site that is designed to be positioned between your gene of interest and the tag to allow the removal of the tag following protein purification or isolation. This plasmid contains a EKT cleavage tag. The protein sequence of the cleavage tag is: DDDDK. Enterokinase (EKT) protease cleaves after the Lysine residue. It can cleave at other basic residues but this is dependent on protein confirmation. If a proline follows the site it will not cut. None of our products contain a proline after the site.

Promoter Expression Level: This plasmid contains a constitutive bacterial promoter that does not require induction. It is the strongest bacterial promoter we sell and this can cause solubility and expression problems with some proteins. We also offer a range of other bacterial promoters that are compatible with this plasmid and are available on request.

Notch3 interactome analysis identified WWP2 as a negative regulator of Notch3 signaling in ovarian cancer.

Jin-Gyoung Jung et al.

PLoS genetics, 10(10), e1004751-e1004751 (2014-10-31)

The Notch3 signaling pathway is thought to play a critical role in cancer development, as evidenced by the Notch3 amplification and rearrangement observed in human cancers. However, the molecular mechanism by which Notch3 signaling contributes to tumorigenesis is largely unknown.

The GTP- and Phospholipid-Binding Protein TTD14 Regulates Trafficking of the TRPL Ion Channel in Drosophila Photoreceptor Cells.

Alexander C Cerny et al.

PLoS genetics, 11(10), e1005578-e1005578 (2015-10-29)

Recycling of signaling proteins is a common phenomenon in diverse signaling pathways. In photoreceptors of Drosophila, light absorption by rhodopsin triggers a phospholipase Cβ-mediated opening of the ion channels transient receptor potential (TRP) and TRP-like (TRPL) and generates the visual

Dickkopf-3 regulates prostate epithelial cell acinar morphogenesis and prostate cancer cell invasion by limiting TGF-β-dependent activation of matrix metalloproteases.

Diana Romero et al.

Carcinogenesis, 37(1), 18-29 (2015-10-28)

Dickkopf-3 (Dkk-3) is a secreted protein whose expression is downregulated in many types of cancer. Endogenous Dkk-3 is required for formation of acini in 3D cultures of prostate epithelial cells, where it inhibits transforming growth factor (TGF)-β/Smad signaling. Here, we

In vivo characterization of the physicochemical properties of polymer-linked TLR agonists that enhance vaccine immunogenicity.

Geoffrey M Lynn et al.

Nature biotechnology, 33(11), 1201-1210 (2015-10-27)

The efficacy of vaccine adjuvants such as Toll-like receptor agonists (TLRa) can be improved through formulation and delivery approaches. Here, we attached small molecule TLR-7/8a to polymer scaffolds (polymer-TLR-7/8a) and evaluated how different physicochemical properties of the TLR-7/8a and polymer
