Small Heat Shock Proteins (sHSPs) are molecular chaperones that transiently interact with other proteins, thereby assisting with quality control of proper protein folding and/or degradation. They are also recruited to protect cells from a variety of stresses in response to extreme heat, heavy metals, and oxidative-reductive stress. Although ten human sHSPs(More)
We investigated whether a cell-penetrating peptide linked via a disulfide bond to a fluorophore-labeled cargo peptide can be used to interrogate changes in cellular redox state. A fluorescence resonance energy transfer (FRET) pair was constructed so that the cargo peptide was labeled with fluorescein amidite (FAM) and the cell-penetrating peptide was(More)
