--- license: unknown tags: - biology - rna - genomics --- # Overview Internal ribosome entry sites (IRESs) enable cap-independent translation initiation. This binary classification dataset contains 46,774 unique sequences: 37,602 non-IRES examples and 9,172 IRES examples. The target corresponds to the source dataset's `IRES_class_600` label. The sequences combine a high-throughput oligo assay with entries from IRESbase, IRESite, Rfam, and the IRESpred training data. The original source collection is retained for each row. The dataset mixes 5' UTR fragments with viral-genome/CDS fragments, known IRES mutants, synthetic constructs, and controls. This dataset is redistributed as part of mRNABench: https://github.com/morrislab/mRNABench # Data Format Description of data columns: - `transcript_id`: Identifier supplied by the source dataset. - `sequence`: Candidate IRES sequence using the DNA alphabet. - `cds`: Length-matched all-zero track because consistent coding-sequence annotations are unavailable. - `splice`: Length-matched all-zero track because consistent splice-junction annotations are unavailable. - `target`: Binary IRES activity label, where `1` is IRES and `0` is non-IRES. - `description`: Original sequence collection in `source=` format. # Data Source This dataset is a Hugging Face redistribution of the IRES classification dataset assembled for UTR-LM. It combines multiple source collections with different licensing terms, and no single redistribution license is specified.
