Rapid protein stability prediction using deep learning representations

Introduction

This repository contains scripts and data to repeat the analyses in Blaabjerg et al.: "Rapid protein stability prediction using deep learning representations".

Code

Overview of files:

  • src/run_pipeline.py - Main script for repeating the analyses in paper.
  • src/rasp_model.py - Classes for models and data.
  • src/helpers.py - Various helper functions.
  • src/visualization.py - Functions for plotting results.
  • src/pdb_parser_scripts/ - Scripts for parsing PDBs.

Installation

Tested on Linux using Miniconda with package versions specified below.

  1. Clone this repository.

  2. Install and activate conda environment with requirements:
    conda create --name rasp-model python=3.6
    conda activate rasp-model
    conda install pyyaml=5.3.1 pandas=1.1.4 scipy=1.5.3 numpy=1.17.3 scikit-learn=0.24.0 mpl-scatter-density=0.7 pdbfixer=1.5 pytorch=1.2.0 cudatoolkit=10.0 biopython=1.72 openmm=7.3.1 matplotlib=3.1.1 seaborn=0.11.2 ptitprince=0.2.5 dssp=3.0.0 vaex=4.5.0 -c salilab -c omnia -c conda-forge -c anaconda -c defaults

  3. Install reduce in the right directory. This program is used by the parser to add missing hydrogens to the proteins.
    cd src/pdb_parser_scripts
    git clone https://github.com/rlabduke/reduce.git
    cd reduce/
    make; make install # This might give an error but provides the reduce executable in this directory.

  4. Download the data file rasp_preds_exp_strucs_gnomad_clinvar.csv from https://sid.erda.dk/sharelink/fFPJWflLeE and add it to the directory data/test/Human/.

  5. Download the Vaex data file rasp_preds_alphafold_UP000005640_9606_HUMAN_v2_vaex_dataframe.zip from https://sid.erda.dk/sharelink/fFPJWflLeE and add it to the directory data/test/Human/. Unpack the file using the command: gunzip rasp_preds_alphafold_UP000005640_9606_HUMAN_v2_vaex_dataframe.zip.

Execution

Execute the pipeline using src/run_pipeline.py.

RaSPLab

The RaSP model can be used in Colab using this link.

Data availability

All data related to the RaSP ddG predictions for the human proteome (alphafold UP000005640_9606_HUMAN_v2) is available at https://sid.erda.dk/sharelink/fFPJWflLeE. Overview of available data files:

  • rasp_preds_alphafold_UP000005640_9606_HUMAN_v2 - Single directory containing all 23,391 human RaSP ddG predictions. Access to individual protein files is available by clicking through the browser interface.
  • rasp_preds_alphafold_UP000005640_9606_HUMAN_v2.zip - Zipped version of the directory above useful for local download.
  • rasp_preds_alphafold_UP000005640_9606_HUMAN_v2_prism_dir - Directory containing RaSP ddG predictions sorted into subdirectories using the PRISM default tree folder structure based on UniProt ID. Example: RaSP prediction file for UniProt ID P12345 will be located in P1/23/45/. Access to individual protein files is available by clicking through the browser interface.
  • rasp_preds_alphafold_UP000005640_9606_HUMAN_v2_prism_dir.zip - Zipped version of the directory above useful for local download.
  • rasp_preds_alphafold_UP000005640_9606_HUMAN_v2_vaex_dataframe.zip - Vaex data file containing all 23,391 human RaSP ddG predictions. The Vaex format enables easy access of data using a single file. Vaex documentation is available here.
  • rasp_preds_exp_strucs_gnomad_clinvar.csv - Selected RaSP ddG predictions mapped to relevant gnomAD and ClinVar annotations.

Data notes

Note that in a few cases, the residue numbering for proteins in the experimental test data has been shifted to align with the residue numbering found in the structural data.
