Pub. Med Vesicular Stomatitis Virus N Protein specific Single domain Antibody Fragments Inhibit Replication. Hanke L, et al., EMBO Rep, 1. Vesicular stomatitis virus VSV single stranded RNA genome is tightly encapsidated by nucleoprotein N to form a nucleocapsid N RNA. N RNA serves as the template for RNA synthesis. In the absence of nucleoprotein N, full length RNAs will not be produced and therefore nucleoprotein N is considered as a target of intervention of the virus life cycle. Described herein is the use of cytosolically expressed variable region of the heavy chain of camelid heavy chain only antibodies VHHs to target the viral nucleoprotein N. Four of the VHHs identified are specific for VSV. Affinity and kinetic parameters were determined by using Bio Layer Interferometry BLI. A Pall Forte. Bio Octet RED9. Streptavidin Biosensor probes was used to perform all BLI experiments. Biosensor tips were loaded with biotinylated WT and escape mutant versions of N RNA variants. Association and dissociation of VHHs were studied over a series of concentrations. Experimental data obtained were fitted using the 2 1 heterogeneous ligand binding global fit model. KD values were determined. The binding sites on nucleoprotein N for some of the identified VHHs were characterized and the information was used to present a molecular explanation for the inhibitory effects of the N specific VHHs. Overall, these findings reveal new features on the N protein surface that may have the potential to be used as an antiviral intervention options. Pub. Med Tumor secreted Anterior Gradient 2 Binds to VEGF and FGF2 and Enhances Their Activities by Promoting Their Homodimerization. Guo H, et al., Oncogene, doi 1. Human anterior gradient 2 AGR2 is a protein that overexpresses in human adenocarcinomas. The exact function of secreted AGR2, including its mechanism of action is not well understood. Reported herein is the mechanism for the tumor promoting function of extracellular AGR2. Furthermore, authors demonstrate that extracellular AGR2 directly binds to vascular endothelial growth factor VEGF and fibroblast growth factor 2 FGF2 and amplify their activities. Binding affinity of AGR2 to various growth factors were studied by using the Bio Layer Interferometry BLI. A Pall Forte. Bio Octet RED9. Ni NTA biosensors was used to perform all BLI experiments. Biosensor tips were immobilized with His AGR2. Subsequently, the AGR2 loaded biosensor tips were dipped in solutions of VEGF1. VEGF1. 65, VEGF1. FGF2, EGF, IGF 1 and TGF1, respectively. KD values were determined for all the binding interactions. Collectively, findings of this investigation suggest that the secreted AGR2 is a promising antitumor target, which affects the function of extracellular signaling networks. Pub. Med Structural Basis for Dimerization and RNA Binding of Avian Infectious Bronchitis Virus nsp. Hu T, et al., Protein Sci, 2. Coronaviruses Co. Vs are positive strand RNA viruses with an ability to infect animals as well as humans. Co.
