TR-FRET Assays of Huntingtin Protein Fragments Reveal Temperature and PolyQ Length-Dependent Conformational Changes
Time-Resolved Fluorescence Resonance Energy Transfer (TR-FRET) technology is a widely used immunoassay that enables high-throughput quantitative measurements of proteins of interest. One of the well established examples is the TR-FRET assay for mutant huntingtin protein (HTT), which is the major cause of the neurodegenerative Huntington's disease (HD). To measure the mutant HTT protein, the pub...
متن کاملUsing FLIM-FRET to Measure Conformational Changes of Transglutaminase Type 2 in Live Cells
Transglutaminase type 2 (TG2) is a ubiquitously expressed member of the transglutaminase family, capable of mediating a transamidation reaction between a variety of protein substrates. TG2 also has a unique role as a G-protein with GTPase activity. In response to GDP/GTP binding and increases in intracellular calcium levels, TG2 can undergo a large conformational change that reciprocally modula...
متن کاملMD simulations and FRET reveal an environment-sensitive conformational plasticity of importin-β.
The nuclear pore complex mediates nucleocytoplasmic transport of macromolecules in eukaryotic cells. Transport through the pore is restricted by a hydrophobic selectivity filter comprising disordered phenylalanine-glycine-rich repeats of nuclear pore proteins. Exchange through the pore requires specialized transport receptors, called exportins and importins, that interact with cargo proteins in...
متن کاملConformational changes in intact dengue virus reveal serotype-specific expansion
Dengue virus serotype 2 (DENV2) alone undergoes structural expansion at 37 °C (associated with host entry), despite high sequence and structural homology among the four known serotypes. The basis for this differential expansion across strains and serotypes is unknown and necessitates mapping of the dynamics of dengue whole viral particles to describe their coordinated motions and conformational...
متن کاملAnother Bridge to Cross
In choosing this quote, from VuginiaWoolf, to begin The Sexual Politics of Meat: A Feminist-Vegetarian Critical Theory, Carol Adams appropriately highlights certain central characteristics of contemporary feminist thought and thus locates her own work frrmly in the tradition of feminist theorizing. By pointing out the impossibility and lack of desirability in renunciation, Adams through Woolf p...
