## Multifaceted Protein-Protein Interaction Prediction Based on Siamese Residual RCNN

This is the repository for PIPR (originally Lasagna in our previous preprint version). This repository contains the source code and links to some datasets used in our paper.

## Abstract

Sequence-based protein–protein interaction (PPI) prediction represents a fundamental computational biology problem. To address this problem, extensive research efforts have been

made to extract predefined features from the sequences. Based on these features, statistical algorithms are learned to classify the PPIs. However, such explicit features are usually costly to extract, and typically have limited coverage on the PPI information. We present an end-to-end framework, PIPR (Protein–Protein Interaction Prediction Based on Siamese Residual RCNN), for PPI predictions using only the protein sequences. PIPR incorporates a deep residual recurrent convolutional neural network in the Siamese architecture, which leverages both robust local features and contextualized information, which are significant for capturing the mutual influence of proteins sequences. PIPR relieves the data pre-processing efforts that are required by other systems, and generalizes well to different application scenarios. Experimental evaluations show that PIPR outperforms various state-of-the-art systems on the binary PPI prediction problem. Moreover, it shows a promising performance on more challenging problems of interaction type prediction and binding affinity estimation, where existing approaches

fall short.

## Environment

    python 2.7 or 3.6

    Tensorflow 1.7 (with GPU support)

    CuDNN (if not installed, all CuDNNGRU in the source code needs to be changed to GRU)

    Keras 2.2.4

[Here](https://github.com/muhaochen/seq_ppi/blob/master/environment/py36.yml) is a yml file of the environment.

## Folders

./binary contains the implementation for the binary prediction task. This includes scripts to run on three datasets: Yeast, Human and multi-species.    

./type contains that for the interaction type prediction task.  

./regression contains that for the binding affinity prediction task. 

Each folder is attached with a **run.sh** to show how to run the evaluation program.  

./embeddings contains pre-trained amino acid embeddings and the training script.  

## Datasets

Here we include altogether 6 datasets. New datasets processed in this work are marked *ND*.  

1. The Yeast dataset for binary PPI prediction provided in [Guo et al. 2008](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2396404/).  

2. The *multi-species dataset (C. elegans, D. melanogaster and E. coli)* extracted from DIP for binary PPI prediction. (*ND*)  

3. Added another binary PPI prediction dataset from [Pan et el. 2010](https://www.ncbi.nlm.nih.gov/pubmed/20698572) under the folder *sun*.  

4. The SHS27k dataset for interaction type prediction can be downloaded from [here](http://yellowstone.cs.ucla.edu/~muhao/pipr/SHS_ppi_beta.zip) or from the [Google Drive](https://drive.google.com/open?id=1y_5gje6AofqjrkMPY58XUdKgDuu1mZCh). (*ND*)  

5. The larger SHS148k dataset for interaction type prediction can be found in the links above. (*ND*)  

6. Link to the normalized SKEMPI dataset is [here](http://yellowstone.cs.ucla.edu/~muhao/pipr/SKEMPI_all_dg_avg_(PIPR).zip) or from the [Google Drive](https://drive.google.com/file/d/1XfcG8Ub-KaDxCT6JCb74BzXAY5QLCcEQ/view?usp=sharing).  

### Note: if you would like to use another PPI dataset of your own, then each id2seq_file in rcnn.py needs to be changed to a corresponding dictionary file.
