Web9 mrt. 2024 · Therefore, while hyperphosphorylation at some sites may prevent aggregation by improving TDP-43’s solubility and repulsing it from other phosphorylated protein, it could also impair its degradation by protein turn over systems within the cell.
Hyperphosphorylation tunes TDP-43 solubility - PubMed
Web30 apr. 2024 · Cellular experiments show that phosphomimetic substitutions do not affect nuclear import or RNA regulatory functions of TDP-43, but suppress accumulation of TDP-43 in membrane-less organelles and promote its solubility in neurons. We propose that TDP-43 hyperphosphorylation may be a protective cellular response to counteract … Web2 nov. 2024 · Again, since endogenous TDP-43 was predominantly soluble in 293T cells, the effect on TDP-43 solubility was assessed with the transiently overexpressed TDP-43-HA in the subsequent experiments. We found that KD of CHMP2B reduced ( Fig. 2, i and j ), whereas OE of WT CHMP2B or CHMP2B Intron5 increased ( Fig. 2, k and l ), the … gourock to rothesay
