# Model Overview ## Description: ProteinMPNN (Protein Message Passing Neural Network) is a deep learning-based graph neural network designed to predict amino acid sequences for given protein backbones. This network leverages evolutionary, functional, and structural information to generate sequences that are likely to fold into the desired 3D structures.
This model is available for commercial use.

# Training & Evaluation: ## Training Dataset: **Link:** [The Protein Data Bank](https://www.rcsb.org/)
** Data Collection Method by dataset
* Hybrid: Automatic, Human
For PDB dataset, scientists worldwide submit structural data determined by X-ray crystallography or cryo-electron microscopy (cryo-EM). This includes atomic coordinates, experimental data, and metadata about the biological macromolecules.
** Labeling Method by dataset
* Hybrid: Automatic, Human
For PDB dataset, expert biocurators review the submitted data to ensure accuracy and completeness. This involves checking the plausibility of the data and annotating it with relevant biological and chemical information. CATH 4.1 dataset is derived from the PDB dataset. The CATH (Class, Architecture, Topology, Homologous superfamily) database hierarchically classifies protein domain structures that are obtained from protein structures deposited in the PDB. The data in CATH are specifically sourced from PDB files and include structures determined at a resolution of 4 angstrom or better. The classification process involves both manual and automated methods to ensure accurate domain identification and classification. For ProteinMPNN, the data underwent quality filtering to ensure high accuracy, this involved removing structures with low resolution and potential errors.
**Properties (Quantity, Dataset Descriptions, Sensor(s)):** Model was trained by Institute for Protein Design. The dataset for training consisted of 23,358 sequences. Dataset: CATH 4.2, PDB. Sensors: X-ray crystallography, cryoEM.
## Evaluation Dataset: ** Data Collection Method by dataset
* Automatic: random splits from PDB dataset.
** Labeling Method by dataset
* Automatic: random splits from PDB dataset.
The training, validation, and test splits were derived from protein assemblies in the PDB, which includes structures determined by X-ray crystallography or cryo-electron microscopy (cryoEM). The dataset was divided into random splits with 23,358 sequences for training, 1,464 for validation, and 1,529 for testing.
