# PSR: Protein Structure Ranking |
|
|
|
|
|
## Overview |
|
|
|
This task relates to predicting the three-dimensional structure of a protein |
|
molecule, given its sequence. A total of around 700 protein targets are included, |
|
which consist of protein targets from Critical Assessment of Structure |
|
Prediction (CASP) 5-13. |
|
|
|
We phrase this problem as decoy ranking. For each protein target, we |
|
include its decoys sets compiled from the CASP decoy sets released for the |
|
Model Quality Assessment (MQA). We relax those structures with the SCWRL4 |
|
software (Krivov and Dunbrack, 2019) to improve side-chain conformations. For |
|
each decoy, we calculate the RMSD, TM-score, GDT_TS, and GDT_HA scores to the |
|
experimentally determined structure using the TM-score software (Zhang and |
|
Skolnick, 2007). |
|
|
|
|
|
## Datasets |
|
- splits: |
|
- split-by-year: This dataset contains data in the CASP dataset, but is split |
|
temporally. More specifically, we randomly split the targets in CASP5-10 and |
|
randomly sample 50 decoys for each target to generate the training and validation |
|
sets (508 targets for training, 56 targets for validation), and use the CASP11 |
|
Stage 2 as test set (85 targets total, with 150 decoys for each target, excluding |
|
the native structures). |
