Mutation Stability Prediction

Overview

The Mutation Stability Prediction (MSP) task involves classifying whether mutations in the SKEMPI 2.0 database (J. Jankauskaite, B. Jiménez-García et al., 2019) are stabilizing or not using the provided protein structures.

Each mutation in the MSP task includes a PDB file with the residue of interest transformed to the specified mutant amino acid as well as the native PDB file.

A total of 4148 mutant structures accompanied by their 316 WT structures are provided.

Non-point mutations or mutants that caused non-binding of the complex were screened out from SKEMPI. Additionally, mutations involving a disulfide bond and mutants from the PDBs 1KBH or 1JCK were ignored due to processing difficulties. A label of 1 was assigned to a mutant if the Kd of the mutant protein was less than that of the wild-type protein, indicating better binding, and 0 otherwise. If a mutant had multiple conflicting stability results in the original data, the first result seen when processing the SKEMPI dataset was used.

Format

Each item in the dataset contains the following keys:

['input_ids'] The set of atomic numbers for both the mutated and original atoms concatenated together. ['coords'] The 3D coordinates for both the mutated and original atoms concatenated together. ['label'] 1 for better binding, 0 for worse or equal. ['token_type_ids'] A mask that corresponds to which inputs_ids/coords belong to the mutated or original atoms (0 for mutated , 1 for original)
