This is the repository for the NAR Genom. Bioinform. paper "Mutation effect estimation on protein-protein interactions using deep contextualized representation learning" (MuPIPR). This repository contains the source code and links to some datasets used in our paper. (to be updated)

MuPIPR can be run under Linux. The following packages are required: python 3.6, h5py, Tensorflow 1.7 (with GPU support), Keras 2.2.4 and bilm-tf.

If you don't have python 3.6, please download from here.

Then you can use pip install to install the following packages:

h5py
Tensorflow 1.7 (with GPU support)
Keras 2.2.4

Make sure tensorflow and h5py has been installed successfully before you install bilm-tf. To install bilm-tf, please download the package from [here] (https://github.com/allenai/bilm-tf) and run: python setup.python

• biLM: contains the pre-trained language models for contextualized amino acid representations.
• data: contains the datasets and processing scripts for the two tasks.
• model: contains the implementation for MuPIPR.

We obtain the corpus to pre-train the BiLSTM language model from the STRING database. A total of 66235 protein sequences of four most frequent species from the SKEMPI database are extracted, i.e. Homo sapiens, Bos taurus, Mus musculus and Escherichia coli. These are the four most frequent species in the SKP1402m dataset.

To serve the pre-trained contextualized embedding model to MuPIPR, please download and unzip the model.zip file in the biLM folder.

Please refer to the readme in the data folder and the model folder, respectively.

This work has been published in the NAR Genomics and Bioinformatics journal.
