WebIn 1994, scientists interested in protein folding formed CASP (Critical Assessment of protein Structure Prediction). CASP is a community forum that allows researchers to share progress on the protein-folding problem. The community also organises a biennial challenge for research groups to test the accuracy of their predictions against real experimental data.

WebDec 5, 2024 · Protein folding is the process by which a protein takes its shape from a string of building blocks to its final three-dimensional structure, which determines its function. By better predicting how proteins take their structure, or "fold," scientists can more quickly develop drugs that, for example, block the action of crucial viral proteins. WebWhile drug resistance mutations can often be attributed to the loss of direct or solvent-mediated protein−ligand interactions in the drug-mutant complex, in this study we show that a resistance mutation for the picomolar HIV-1 capsid (CA)-targeting antiviral (GS-6207) is mainly due to the free energy cost of the drug-induced protein side chain reorganization in …
