A biosensor to gauge protein homeostasis resilience differences in the nucleus compared to cytosol of mammalian cells

Authors : Raeburn, Candice B. (2021)

An extensive network of chaperones and other proteins maintain protein homeostasis and guard against inappropriate protein aggregation that is a hallmark of neurodegenerative diseases. Using a fluorescence resonance energy-based biosensor that simultaneously reports on intact cellular chaperone holdase activity and detrimental aggregation propensity, we investigated the buffering capacity of the systems managing protein homeostasis in the nucleus of the human cell l...

Identifying Selectivity Filters in Protein Biosensor for Ligand Screening

Authors : Sahil, Mohammad (2023)

Bacterial transcription initiation mainly occurs via two diverse RNA polymerases, namely 70 and 54. While 70 polymerase transcribes housekeeping genes and does not require any external activation to form transcriptionally competent open complex, the alternate polymerase 54 require regulatory proteins, typically AAA+ ATPases, that aid in converting the closed RNA polymerase complex to an active open state.1,2 External stimuli and enviro...
