Electrostatic Repulsion Governs TDP-43 C-terminal Domain Aggregation

PLoS Biol. 2016 Apr 20;14(4):e1002447. doi: 10.1371/journal.pbio.1002447. eCollection 2016 Apr.

Abstract

TDP-43 is a protein that forms aggregates implicated in amyotrophic lateral sclerosis. In response to a recent study, this Formal Comment argues that the pH-dependent solubility of this protein is better explained by the mutual repulsion of charged groups than by the formation of hydrogen bonds.
