PDB files of "Characterization of ligand-induced thermal stability of the human organic cation transporter 2 (OCT2)"
<p>The predicted alphafold structure of OCT2 (Uniprot O15244) was embedded in a DPPC model membrane, solvated with TIP3P water and subjected to 250 ns molecular dynamics simulation using the Desmond module of Schroedingers Drug Discovery Suite. The last 150 ns were used for clustering and the cluster with most of the members (cluster0) was selected as a model for OCT2. Based on that (still predicted, but optimised) model we performed docking with various substrates for which we also provide the obtained docking pose. See Publication in Frontiers in Pharmacology (DOI: 10.3389/fphar.2023.1154213) for details and results.</p>
