TDP-43 domain structures. The NTD monomer consists of six β-strands and a single α-helix arranged in a ubiquitin-like β-grasp fold, similar to the DIX domain of Axin 1 ( Mompeán et al., 2016c; Figure 2A ). The DIX domain is known to facilitate both homo- and hetero-oligomerization ( Kishida et al., ).

The structure of the TDP-43 amino end (purple) neatly aligns with that of ubiquitin (yellow). [Image courtesy of Qin et al., PNAS.] TDP-43, like many proteins involved in neurodegeneration, confounds structural biologists with its aggregation, Song wrote. In TDP-43, the amino terminus has the highest propensity to cluster, he added.

TDP-43 α-helical structure tunes liquid-liquid phase separation and

While some ALS-associated mutations in TDP-43 disrupt self-interaction and function, here we show that designed single mutations can enhance TDP-43 assembly and function via modulating helical structure. Using molecular simulation and NMR spectroscopy, we observe large structural changes upon dimerization of TDP-43.

Study: Altering TDP-43's Structure Halts Neurodegeneration in ALS, FTD

Accumulation of TDP-43 protein is known to drive neurodegeneration associated with amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Now, researchers have found that targeting the structure of TDP-43 and blocking its normal activity can halt the death of nerve cells linked to TDP-43 accumulation in ALS and FTD models.
