Conformational Filtering in Polypeptides and Proteins

Journal of Molecular Biology, 1993
We present a method for assigning an ensemble of conformational states to each amino acid residue of a sequence. The states are defined as regions in the (phi, psi) map. The procedure is based on the use of conformational filters. In each filter we use a different set of approximations to estimate the probability of conformational states, and retain ...

Random walks in the space of conformations of toy proteins

, 1999
Monte Carlo dynamics of the lattice 48 monomers toy protein is interpreted as a random walk in an abstract (discrete) space of conformations. To test the geometry of this space, we examine the return probability $P(T)$, which is the probability to find ...

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Protein conformation and disease.

Veterinary research, 1996
In a number of neurodegenerative diseases, a change in the conformation of specific proteins occurs which is considered to be related to the development of the disease process. In general, a change in the protein conformation from a predominantly alpha-helical to a predominantly beta-sheet structure, due to genetic or environmental factors, leads to ...

Investigating the cell of origin and novel molecular targets in Merkel cell carcinoma: a historic misnomer

Molecular Oncology, EarlyView.
This study indicates that Merkel cell carcinoma (MCC) does not originate from Merkel cells, and identifies gene, protein & cellular expression of immune‐linked and neuroendocrine markers in primary and metastatic Merkel cell carcinoma (MCC) tumor samples, linked to Merkel cell polyomavirus (MCPyV) status, with enrichment of B‐cell and other immune cell

YAP1::TFE3 mediates endothelial‐to‐mesenchymal plasticity in epithelioid hemangioendothelioma

Molecular Oncology, EarlyView.
The YAP1::TFE3 fusion protein drives endothelial‐to‐mesenchymal transition (EndMT) plasticity, resulting in the loss of endothelial characteristics and gain of mesenchymal‐like properties, including resistance to anoikis, increased migratory capacity, and loss of contact growth inhibition in endothelial cells.

Investigation of conformational changes of cathepsin B as a feasibility assessment for NaCl reduction in Jinhua ham

Food Science and Human Wellness
To regulate the sodium chloride content in Jinhua ham, the impact of NaCl on the activity and conformation of cathepsin B was investigated using spectroscopy and computational methods. The results showed that the activity of cathepsin B decreased with an
