Research: CANCER Folding Project #18113

18110: simulation for the complex of KRas(G12D)-GDP-KRpep-2d, with the initial structure of peptide ligand in the known binding position, exploring the binding dynamics of the complex and binding poses. 18111: binding simulation for the complex of KRas(G12D)-GDP-KRpep-2d, with the initial structure of peptide ligand 35A away from the protein center, exploring if the correct binding pose will be observed through the simulation. 18112-18114: binding simulation for the complex of KRas(G12D)-GDP-peptide, the binding pocket and binding pose is unknown.

We start with 100 randomly sampled initial structures, in each structure, the ligand center is 40A away from the protein center, with random direction and rotation.

The simulation is aimed to identify potential binding pocket and binding poses of the peptide.

The interactions between KRas protein and the peptide would provide insights in designing small molecules that bind with KRas. This is a project run by Roivant Sciences (formerly Silicon Therapeutics) as was officially announced in this press release: https://foldingathome.org/2021/04/20/maximizing-the-impact-of-foldinghome-by-engaging-industry-collaborators/ All data is being made publicly available in real time at https://console.cloud.google.com/storage/browser/stxfah-bucket.
