Simulations for: Patched 1 regulates Smoothened by controlling sterol binding to its extracellular cysteine-rich domain.

<strong>Atomistic simulations of Smoothened:</strong> Atomistic molecular dynamics simulations of glycosylated mouse Smoothened (mSMO) and human Smoothened (hSMO) in distinct liganded states: - mSMO in an apo state (mSMO_apo) - mSMO with TMD cholesterol bound (mSMO_chol_TMD) - mSMO with CRD cholesterol bound (mSMO_chol_CRD) - mSMO with cholesterol bound to the CRD and TMD (mSMO_2chol_TMD_CRD) - mSMO bound to CRD cholesterol and Smoothened agonist (SAG) (mSMO_chol_CRD_SAG) - mSMO bound to CRD and TMD cholesterols, SAG and an intracellular nanobody (mSMO_2chol_SAG_nanobody) - mSMO bound to CRD and TMD cholesterol and with an additional cholesterol bound at a proposed 'mid' position (mSMO_3chol) - hSMO bound to CRD cholesterol and SAG (hSMO_chol_CRD_SAG) All simulations were run for 5x 300 ns. The active mSMO conformation was obtained from the Protein Data Bank (PDB ID: 6O3C). The hSMO structure was determined using X-ray crystallography as outlined within this study. <strong>File description for each system:</strong> - md_fit_firstframe.pdb : Initial frame used for atomistic simulations (replicate 1, each replicate equilibrated independently). - md_fit_<em>X</em>.xtc : Gromacs trajectory file for each replicate (X=replicate number).
