background permanent antigenic variation of influenza viruses causes a major concern to develop an effective human influenza vaccine. conserved antigens are new vaccine candidates because it is not necessary to match the prepared vaccine with circulating strains. ion channel m2 protein is conserved among all influenza a viruses, allowing the virus to enter host cells. objectives to prepare an e...

PURPOSE Crystallins are major functional and structural proteins in mammalian lens. Their expression, distribution, and protein-protein interaction affect lens development and fiber cell differentiation. Mutated crystallins lead to structural and functional changes of lens structure and could lead to opacity formation and cataract development. The purpose of this study was to investigate the bi...

Protein aggregation is believed to occur through the formation of misfolded conformations. It is expected that, in order to minimize aggregation, an effective small molecule chaperone would destabilize these intermediates. To study the mechanism of a chemical chaperone, we have designed a series of mutant proteins in which a tryptophan residue experiences different local environments and solven...

Translational control permits cells to respond swiftly to a changing environment. Rapid attenuation of global protein synthesis under stress conditions has been largely ascribed to the inhibition of translation initiation. Here we report that intracellular proteotoxic stress reduces global protein synthesis by halting ribosomes on transcripts during elongation. Deep sequencing of ribosome-prote...

Green fluorescent protein (GFP) has been widely used in several molecular and cellular biology applications, since it is remarkably stable in vitro and in vivo. Interestingly, native GFP is resistant to the most common chemical denaturants; however, a low fluorescence signal has been observed after acid-induced denaturation. Furthermore, this acid-denatured GFP has been used as substrate in stu...
