Monoclonal Antibodies as Probes to Study Ligand-Induced Conformations of Troponin Subunits

open access: yesFrontiers in Physiology, 2022
Striated muscle contraction and relaxation is regulated by Ca2+ at the myofilament level via conformational modulations of the troponin complex. To understand the structure–function relationship of troponin in normal muscle and in myopathies, it is ...

Infrared spectroscopy analysis determining secondary structure change in albumin by cerium oxide nanoparticles

open access: yesFrontiers in Toxicology, 2023
Cerium oxide (CeO2) nanoparticles are expected to have applications in the biomedical field because of their antioxidative properties. Inorganic nanoparticles interact with proteins at the nanoparticle surface and change their conformation when ...

A New Function for Amyloid-Like Interactions: Cross-Beta Aggregates of Adhesins form Cell-to-Cell Bonds

open access: yesPathogens, 2021
Amyloid structures assemble through a repeating type of bonding called “cross-β”, in which identical sequences in many protein molecules form β-sheets that interdigitate through side chain interactions.

How Staying Negative Is Good for the (Adult) Brain: Maintaining Chloride Homeostasis and the GABA-Shift in Neurological Disorders

open access: yesFrontiers in Molecular Neuroscience, 2022
Excitatory-inhibitory (E-I) imbalance has been shown to contribute to the pathogenesis of a wide range of neurodevelopmental disorders including autism spectrum disorders, epilepsy, and schizophrenia.

Translation from the Ribosome to the Clinic: Implication in Neurological Disorders and New Perspectives from Recent Advances

open access: yesBiomolecules, 2019
De novo protein synthesis by the ribosome and its multitude of co-factors must occur in a tightly regulated manner to ensure that the correct proteins are produced accurately at the right time and, in some cases, also in the proper location.

Tracing conformational changes in proteins [PDF]

open access: yes2009 IEEE International Conference on Bioinformatics and Biomedicine Workshop, 2009
Many proteins undergo extensive conformational changes as part of their functionality. Tracing these changes is important for understanding the way these proteins function. Traditional biophysics-based conformational search methods require a large number of calculations and are hard to apply to large-scale conformational motions.In this work we ...

Novel ADAMTS13 mutations in a patient with congenital thrombotic thrombocytopenic purpura

open access: yesHematology, 2023
Congenital thrombotic thrombocytopenic purpura (TTP) is a rare autosomal recessive genetic disorder caused by mutations in the ADAMTS13 gene. Approximately 200 mutations of the ADAMTS-13 gene have been identified, although only a few have been ...

Dependence of protein-induced lipid bilayer deformations on protein shape [PDF]

open access: yes, 2022
Membrane proteins typically deform the surrounding lipid bilayer membrane, which can play an important role in the function, regulation, and organization of membrane proteins. Membrane elasticity theory provides a beautiful description of protein-induced lipid bilayer deformations, in which all physical parameters can be directly determined from ...

Aβ Secretion and Plaque Formation Depend on Autophagy

open access: yesCell Reports, 2013
Alzheimer’s disease (AD) is a neurodegenerative disease biochemically characterized by aberrant protein aggregation, including amyloid beta (Aβ) peptide accumulation. Protein aggregates in the cell are cleared by autophagy, a mechanism impaired in AD. To
