The proximity-based protein interactome and regulatory logics of the transcription factor p65 NF-κB/RELA.

The protein interactome of p65/RELA, the most active subunit of the transcription factor (TF) NF-κB, has not been previously determined in living cells. Using p65-miniTurbo fusion proteins and biotin tagging, we identify >350 RELA interactors from untreated and IL-1α-stimulated cells, including many TFs (47% of all interactors) and >50 epigenetic regulators belonging to different classes of chromatin remodeling complexes. A comparison with the interactomes of two point mutants of p65 reveals that the interactions primarily require intact dimerization rather than DNA-binding properties.

In People with Subacute Mild Traumatic Brain Injury, earlier Physical Therapy Improved Symptoms at a Faster Rate than Later Physical Therapy: Randomized Controlled Trial.

Importance: There is unclear evidence on when to initiate physical therapy after mild traumatic brain injury (mTBI) in non-athlete, adult population.

Objective: The objective of this study was to investigate physical therapy timing after mTBI through changes in patient-reported and clinically-assessed tools and objective and mechanism measurements of sensorimotor balance control.

Design: This study was an investigator-blinded randomized control trial (NCT03479541).

Localization and regulation of yeast aldehyde dehydrogenase Ald4p structures.

Previously, we identified yeast strains, namely SWORD, showing more robust Ald4p-GFP filament formation than the typical strains. Here, we report that Ald4p-GFP in SWORD strains favorably polymerize into gigantic structures in the cytoplasm, despite the enzyme being established as a mitochondrial resident. In addition, we have found that nocodazole, a microtubule destabilizer, has no effect on Ald4p high-order assembly, suggesting no direct association between microtubule dynamics and Ald4p structure formation.
