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 is an important pathological protein that aggregates in the diseased neuronal cells and is linked to various neurodegenerative disorders. In normal cells, TDP-43 is primarily an RNA-binding protein; however, how the dimeric TDP-43 binds RNA via its two RNA recognition motifs, RRM1 and RRM2, is not clear Macromolecules Proteins 1

03/02/2022 · Scientists analyzed aggregated TDP-43 extracted from the donated brains of two ALS patients with FTD. Using a technique called cryo-electron microscopy, they deduced the structure of the aggregates with a resolution of up to 2.6 angstroms. One angstrom is equal to one hundred-millionth of a centimeter.

TDP-43 encodes an alternative-splicing regulator with tandem RNA-recognition motifs (RRMs). The protein regulates cystic fibrosis transmembrane regulator (CFTR) exon 9 splicing through binding to long UG-rich RNA sequences and is found in cytoplasmic inclusions of several neurodegenerative diseases. We solved the solution structure of the TDP
