Default Common molecular pathogenesis of disease-related intrinsically disordered proteins revealed by NMR analysis.

Common molecular pathogenesis of disease-related intrinsically disordered proteins revealed by NMR analysis.

Common molecular pathogenesis of disease-related intrinsically disordered proteins revealed by NMR analysis.

J Biochem. 2017 Sep 11;:

Authors: Shigemitsu Y, Hiroaki H

Abstract
Intrinsically disordered proteins (IDPs) are either completely unstructured or contain large disordered regions in their native state; they have drawn much attention in the field of molecular pathology. Some of them substantially tend to form protein self-assemblies, such as toxic or non-toxic aggregates and fibrils, and have been postulated to relate to diseases. These disease-related IDPs include A?(1-42) [Alzheimer's disease (AD)], Tau (AD and tauopathy), ?-synuclein (Parkinson's disease), and p53 (cancer). Several studies suggest that these aggregation and/or fibril formation processes are often initiated by transient conformational changes of the IDPs prior to protein self-assembly. Interestingly, the pathological molecular processes of these IDPs share multiple common features with those of protein misfolding diseases, such as transmissible spongiform encephalopathy (PrPsc) and AL-amyloidosis (VL-domain of ?-immunoglobulin). This review provides an overview of solution NMR techniques that can help analyze the early and transient events of conformational equilibrium of IDPs and folded proteins.

4D Non-uniformly sampled HCBCACON and 1J(NCα)-selective HCBCANCO experiments for the sequential assignment and chemical shift analysis of intrinsically disordered proteins
4D Non-uniformly sampled HCBCACON and 1J(NCα)-selective HCBCANCO experiments for the sequential assignment and chemical shift analysis of intrinsically disordered proteins Abstract A pair of 4D NMR experiments for the backbone assignment of disordered proteins is presented. The experiments exploit 13C direct detection and non-uniform sampling of the indirectly detected dimensions, and provide correlations of the aliphatic proton (Hα, and Hβ) and carbon (Cα, Cβ) resonance frequencies to the protein backbone. Thus, all the chemical shifts regularly used to map the transient...
