Dynamic allostery in the peptide/MHC complex enables TCR neoantigen selectivity

J Ma, CM Ayres, CA Brambley, SS Chandran… - Nature …, 2025 - nature.com
The inherent antigen cross-reactivity of the T cell receptor (TCR) is balanced by high
specificity. Surprisingly, TCR specificity often manifests in ways not easily interpreted from …

Detection of putative ligand dissociation pathways in proteins using site-identification by ligand competitive saturation

W Yu, DJ Weber, AD MacKerell Jr - Journal of Chemical …, 2024 - ACS Publications

Molecular docking and molecular dynamics of hypoxia-inducible factor (HIF-1alpha): towards potential inhibitors

D Reda, AA Elfiky, M Elnagdy… - Journal of Biomolecular …, 2024 - Taylor & Francis
HIF-1α is a primary regulator in the adaptation of cancer cells to hypoxia. The aim was to find
out new inhibitors of the HIF-1α. A molecular dynamic (MD) simulation performed on HIF-1α …

Insights into Translocation of Arginine-Rich Cell-Penetrating Peptides across a Model Membrane

S Choe - The Journal of Physical Chemistry B, 2024 - ACS Publications
It is well-known that membrane deformation and water pores contribute to the spontaneous
translocation of arginine-rich cell-penetrating peptides (CPPs). We confirm this through the …
