Integrative model of the γTuSC-Spc110 complex

This repository pertains to the integrative model of the γTuSC-Spc110 complex based on data from cryo-EM, chemical crosslinking, and X-ray crystallography.

The repository contains input data, scripts for modeling and results including bead models and localization probability density maps. It uses IMP (Integrative Modeling Platform).

Folder structure:

  1. inputs : contains all the input data used for modeling such as PDB files and crosslink files.
  2. scripts : scripts to prep input files, perform sampling, and analysis are provided.
  3. results : contains the models and localization densities of the top cluster.
  4. test : scripts for testing the sampling



There are three independent simulations:

  1. Modeling of one copy of γTuSC bound to Spc110 dimer : gtusc_spc110dimer or dimer
  2. Modeling of one copy of γTuSC bound to Spc110 monomer : gtusc_spc110monomer or monomer
  3. Modeling of two copies of laterally associated γTuSC bound to one Spc110 dimer each : lateral_gtusc_spc110tetramer or tetramer


To run the sampling, run modeling scripts like this

mpirun -np 6 $IMP python scripts/sample/ prod

where $IMP is the setup script corresponding to the IMP installation directory (omit for binary installation)
and SCRIPTNAME can be, for example, gtusc_110dimer_1-220GCN4_nointra110xlinks for the dimer simulations.

50 production runs were performed in the above manner for each of the simulations.


Good scoring models were selected using imp-sampcon as shown in scripts/analysis/

Sampling exhaustiveness tests were performed using imp-sampcon as shown in scripts/analysis/

Crosslink violations were analyzed using scripts/analysis/


For each of the simulations, the following files are in the results directory
