# ESMC Protein Function Predictor

|
| 3 |
An Evolutionary-scale Model (ESM) for protein function prediction from amino acid sequences using the Gene Ontology (GO). Based on the ESM Cambrian Transformer architecture, pre-trained on [UniRef](https://www.uniprot.org/help/uniref), [MGnify](https://www.ebi.ac.uk/metagenomics), and the Joint Genome Institute's database and fine-tuned on the [AmiGO Boost](https://huggingface.co/datasets/andrewdalpino/AmiGO-Boost) protein function dataset, this model predicts the GO subgraph for a particular protein sequence - giving you insight into the molecular function, biological process, and location of the activity inside the cell.

You can also output the gene-ontology (GO) `networkx` subgraph for a given sequence like in the example below. You'll need an up-to-date gene ontology database that you can import using the `obonet` package.
