MUST-CNN: A Multilayer Shift-and-Stitch Deep Convolutional Architecture for Sequence-Based Protein Structure Prediction

Code for the paper "MUST-CNN: A Multilayer Shift-and-Stitch Deep Convolutional Architecture for Sequence-Based Protein Structure Prediction" (AAAI 2016)

Zeming Lin, Jack Lanchantin, Yanjun Qi
University of Virginia

Pytorch based code implementation in folder: Py-MUST-CNN

  • Old version V1 Implementation: Lua Torch based in folder "old-Torch-code"

Data

The data is split up into 2 directories: 4Protein, and cb513. Each directory contains a "data" subdirectory and a "hash" subdirectory. The data subdirectory contains "aa1.dat" which is the raw protein sequence data, as well as each *tag.dat file which are the class labels for each separate class. The data subdir also contains the psi-blast files. The hash subdirectory contains the dictionary numbers for each of the amino acids and class labels.

abstract = {Predicting protein properties such as solvent accessibility and secondary structure from its primary amino acid sequence is an important task in bioinformatics. Recently, a few deep learning models have surpassed the traditional window based multilayer perceptron. Taking inspiration from the image classification domain we propose a deep convolutional neural network architecture, MUST-CNN, to predict protein properties. This architecture uses a novel multilayer shift-and-stitch (MUST) technique to generate fully dense per-position predictions on protein sequences. Our model is significantly simpler than the state-of-the-art, yet achieves better results. By combining MUST and the efficient convolution operation, we can consider far more parameters while retaining very fast prediction speeds. We beat the state-of-the-art performance on two large protein property prediction datasets.},
