# bpRNA-1m
bpRNA-1m is a database of single molecule secondary structures annotated using bpRNA.
## Disclaimer
This is an UNOFFICIAL release of the [bpRNA-1m](https://bprna.cgrb.oregonstate.edu/index.html) by Center for Quantitative Life Sciences of the Oregon State University.
**The team releasing bpRNA did not write this dataset card for this dataset so this dataset card has been written by the MultiMolecule team.**
## Dataset Description
- **Homepage**: https://multimolecule.danling.org/datasets/bprna
- **datasets**: https://huggingface.co/datasets/multimolecule/bprna
- **Point of Contact**: [Center for Quantitative Life Sciences of the Oregon State University](https://cqls.oregonstate.edu)
- **Original URL**: https://bprna.cgrb.oregonstate.edu/index.html

## Column Description
The converted dataset consists of the following columns, each providing specific information about the RNA secondary structures, consistent with the bpRNA standard:
- **id**:
A unique identifier for each RNA entry. This ID is derived from the original `.sta` file name and serves as a reference to the specific RNA structure within the dataset.
- **sequence**:
The nucleotide sequence of the RNA molecule, represented using the standard RNA bases:
- **A**: Adenine
- **C**: Cytosine
- **G**: Guanine
- **U**: Uracil
- **secondary_structure**:
The secondary structure of the RNA represented in dot-bracket notation, using up to three types of symbols to indicate base pairing and unpaired regions, as per bpRNA's standard:
- **Dots (`.`)**: Represent unpaired nucleotides.
- **Parentheses (`(` and `)`)**: Represent base pairs in standard stems (page 1).
- **Square Brackets (`[` and `]`)**: Represent base pairs in pseudoknots (page 2).
- **Curly Braces (`{` and `}`)**: Represent base pairs in additional pseudoknots (page 3).
- **structural_annotation**:
Structural annotations categorizing different regions of the RNA based on their roles within the secondary structure, consistent with bpRNA standards:
- **E**: **External Loop** – Regions that are unpaired and external to any loop or helix.
- **S**: **Stem** – Paired regions forming helical structures.
- **H**: **Hairpin Loop** – Unpaired regions at the end of a stem, forming a loop.
- **I**: **Internal Loop** – Unpaired regions between two stems.
- **M**: **Multi-loop** – Junctions where three or more stems converge.
- **B**: **Bulge** – Unpaired nucleotides on one side of a stem.
- **X**: **Ambiguous** or **Undetermined** – Regions where the structure is unknown or cannot be classified.
- **K**: **Pseudoknot** – Regions involved in pseudoknots, where base pairs cross each other.
- **functional_annotation**:
Functional annotations indicating specific functional elements or regions within the RNA sequence, as defined by bpRNA:
- **N**: **None** – No specific functional annotation is assigned.
- **K**: **Pseudoknot** – Marks nucleotides involved in pseudoknot structures, which can be functionally significant.
## Variations
This dataset is available in two variants:
- [bpRNA-1m](https://huggingface.co/datasets/multimolecule/bprna): The main bpRNA-1m dataset.
- [bpRNA-1m(90)](https://huggingface.co/datasets/multimolecule/bprna-90): bpRNA_1m(90) is a subset of bpRNA_1m containing RNAs with less than 90% sequence similarity.
