### Dataset Summary

The Uniref50 (UR50) dataset version 2021/04 is a biological dataset taken from the Uniprot database: https://www.uniprot.org/

### Supported Tasks and Leaderboards

The UR50 dataset contains 48 Million protein sequences. It is a useful dataset to train protein language models.

### Languages

Proteins

## Dataset Structure

### Data Instances


### Data Fields


### Data Splits

 Train, validation

## Dataset Creation

### Curation Rationale

Substituted FASTA headers by <endoftext> tag.
  The dataset was tokenized using BPE and further split into train and validation datasets (ratio 90/10) choosing random sequences for the latter.
