Abstract
The choice of nucleic acid sequence for a given protein strongly impacts function and is species-specific. Current protein-to-nucleic-acid translation models treat sequences in isolation, often over-favoring frequently used codons. To generate more natural nucleic acid sequences, we introduce PINATA (Phylogenetically Informed protein to Nucleic Acid Translation with sequence Alignment), a model that leverages sequences from related species encoded in multiple sequence alignments (MSAs) to guide prediction. Our architecture leverages evolutionary context and learns species-and protein specific context to make biologically-informed predictions. Evaluated across 61,934 gene trees and 882 species, PINATA generates sequences that mirror the naturally-occurring sequence substantially better than existing language models. PINATA leverages MSA data to improve exact native codon recovery by 17.95 percentage points over existing language models, effectively preserves natural rare-codon nuances, and more closely matches native sequence properties. PINATA maintains strong predictive performance even with limited evolutionary data. While previous methods largely treated sequences from different species in isolation, our method leverages the evolutionary relationships between nucleic acids and proteins across species to create a more biologically-informed translation. We demonstrate that leveraging rich evolutionary data through an biologically-designed method strongly aids in translating protein sequences to nucleic acid sequences across species. We will make data and code publicly available upon publication.
The editor's rubric
- Leverage4 / 5
- A general-purpose tool used across several fields (Adam, ResNet, LoRA, next-generation sequencing).
- Magnitude3 / 5
- Large gain: roughly 2x, or a clear new state of the art on a hard, unsaturated problem.
- Evidence3 / 5
- Solid: multiple benchmarks or cohorts, ablations, fair baselines, released code or data.
- Novelty3 / 5
- A genuinely new approach to an open problem.
- Trajectory2 / 5
- Some room to improve with obvious engineering.
- Stakes2 / 5
- Benefits a professional community (practitioners, clinicians, engineers).
Editor’s rationale
Heuristic triage from title and abstract text only, not a reading of the paper. Cues found: method (we propose, we report); breadth (many tasks); gains (relative gain); novelty (new kind); verification (multiple benchmarks, code released).
