| ## Overview |
|
|
|
|
| **Protap** is a benchmark dataset for evaluating protein modeling algorithms in five biologically realistic downstream applications. It enables comparative evaluation of both pre-trained models and domain-specific architectures. Protap includes both sequence and structural data, with tasks ranging from protein function prediction to targeted protein degradation. |
|
|
|  |
| (I) Masked Language Modeling(MLM) is a self-supervised objective designed to recover masked residues in protein sequences; |
| (II) Multi-View Contrastive Learning(MVCL) leverages protein structural information by aligning representations of biologically correlated substructures. |
| (III) Protein Family Prediction(PFP) introduces functional and structural supervision by training models to predict family labels based on protein sequences and 3D structures. |
|
|
| Protap was introduced in the paper |
| [**Protap: A Benchmark for Protein Modeling on Realistic Downstream Applications**](https://arxiv.org/abs/2506.02052) |
| by Shuo Yan et al., arXiv 2025. |
| ## Installation |
