# Therapeutic Protein Designer AI-guided de novo protein design using RFdiffusion backbone generation, ProteinMPNN sequence optimization, and structure validation for therapeutic protein development. **KEY PRINCIPLES**: 1. **Structure-first** - Generate backbone geometry before sequence 2. **Target-guided** - Design binders with target structure in mind 3. **Iterative validation** - Predict structure to validate designs 4. **Developability-aware** - Consider aggregation, immunogenicity, expression 5. **Evidence-graded** - Grade designs by confidence metrics 6. **Actionable output** - Provide sequences ready for experimental testing 7. **English-first queries** - Always use English terms in tool calls Therapeutic protein design starts with the target interaction. What binding surface do you need to cover? A small pocket = nanobody or peptide. A large flat surface = designed protein. Stability, immunogenicity, and manufacturability constrain the design space. ## LOOK UP, DON'T GUESS When uncertain about any scientific fact, SEARCH databases first rather than reasoning from memory. A database-verified answer is always more reliable than a guess. --- ## COMPUTE, DON'T DESCRIBE When analysis requires computation (statistics, data processing, scoring, enrichment), write and run Python code via Bash. Don't describe what you would do — execute it and report actual results. Use ToolUniverse tools to retrieve data, then Python (pandas, scipy, statsmodels, matplotlib) to analyze it. ## When to Use Apply when user asks to: - Design a protein binder, therapeutic protein, or scaffold - Optimize a protein sequence for function - Design a de novo enzyme - Generate protein variants for target binding --- ## Workflow Overview ``` Phase 1: Target Characterization Get structure (PDB, EMDB cryo-EM, AlphaFold), identify binding epitope Phase 2: Backbone Generation (RFdiffusion) Define constraints, generate >= 5 backbones, filter by geometry Phase 3: Sequence Design (ProteinMPNN) Design >= 8 sequences per backbone, sample with temperature control Phase 4: Structure Validation (ESMFold/AlphaFold2) Predict structure, compare to backbone, assess pLDDT/pTM Phase 5: Developability Assessment Aggregation, pI, expression prediction Phase 6: Report Synthesis Ranked candidates, FASTA, experimental recommendations ``` --- ## Critical Requirements ### Report-First Approach (MANDATORY) 1. Create `[TARGET]_protein_design_report.md` first with section headers 2. Progressively update as designs are generated 3. Output `[TARGET]_designed_sequences.fasta` and `[TARGET]_top_candidates.csv` ### Design Documentation (MANDATORY) Every design MUST include: Sequence, Length, Target, Method, and Quality Metrics (pLDDT, pTM, MPNN score, binding prediction). --- ## NVIDIA NIM Tools | Tool | Purpose | Key Parameter | |------|---------|---------------| | `NvidiaNIM_rfdiffusion` | Backbone generation | `diffusion_steps` (NOT `num_steps`) | | `NvidiaNIM_proteinmpnn` | Sequence design | `pdb_string` (NOT `pdb`) | | `ESMFold_predict_structure` | Fast validation | `sequence` (NOT `seq`) | | `NvidiaNIM_alphafold2` | High-accuracy validation | `sequence`, `algorithm` | | `NvidiaNIM_esm2_650m` | Sequence embeddings | `sequences`, `format` | ### Common Parameter Mistakes | Tool | Wrong | Correct | |------|-------|---------| | `NvidiaNIM_rfdiffusion` | `num_steps=50` | `diffusion_steps=50` | | `NvidiaNIM_proteinmpnn` | `pdb=content` | `pdb_string=content` | | `ESMFold_predict_structure` | `seq="MVLS..."` | `sequence="MVLS..."` | | `NvidiaNIM_alphafold2` | `seq="MVLS..."` | `sequence="MVLS..."` | ### NVIDIA NIM Requirements - **API Key**: `NVIDIA_API_KEY` environment variable required - **Rate limits**: 40 RPM (1.5 second minimum between calls) - AlphaFold2 may return 202 (polling required); RFdiffusion and ESMFold are synchronous --- ## Supporting Tools | Tool | Purpose | Key Parameters | |------|---------|----------------| | `PDBe_get_uniprot_mappings` | Find PDB structures | `uniprot_id` | | `RCSBData_get_entry` | Download PDB file | `pdb_id` | | `alphafold_get_prediction` | Get AlphaFold DB structure | `accession` | | `emdb_search` | Search cryo-EM maps | `query` | | `emdb_get_entry` | Get entry details | `entry_id` | | `UniProt_get_entry_by_accession` | Get target sequence | `accession` | | `InterPro_get_protein_domains` | Get domains | `accession` | --- ## Evidence Grading | Tier | Criteria | |------|----------| | T1 (best) | pLDDT >85, pTM >0.8, low aggregation, neutral pI | | T2 | pLDDT >75, pTM >0.7, acceptable developability | | T3 | pLDDT >70, pTM >0.65, developability concerns | | T4 | Failed validation or major developability issues | --- ## Completeness Checklist - [ ] Target structure obtained (PDB or predicted) - [ ] Binding epitope identified - [ ] >= 5 backbones generated, top 3-5 selected - [ ] >= 8 sequences per backbone, MPNN scores reported - [ ] All sequences validated (ESMFold), pLDDT/pTM reported, >= 3 passing - [ ] Developability assessed (aggregation, pI, expression) - [ ] Ranked candidate list, FASTA file, experimental recommendations --- ## Reference Files - **DESIGN_PROCEDURES.md** - Phase-by-phase code examples, sampling parameters, fallback chains - **TOOLS_REFERENCE.md** - Complete tool documentation with code examples - **EXAMPLES.md** - Sample design workflows and outputs - **CHECKLIST.md** - Detailed phase checklists and quality metrics - **design_templates.md** - Report templates and output format examples

tooluniverse
Router skill for ToolUniverse tasks. First checks if specialized tooluniverse skills (105+ skills covering disease/drug/target research, gene-disease associations, clinical decision support, genomics, epigenomics, proteomics, comparative genomics, chemical safety, toxicology, systems biology, and more) can solve the problem, then falls back to general strategies for using 2300+ scientific tools. Covers tool discovery, multi-hop queries, comprehensive research workflows, disambiguation, evidence grading, and report generation. Use when users need to research any scientific topic, find biological data, or explore drug/target/disease relationships. ALSO USE for any biology, medicine, chemistry, pharmacology, or life science question — even simple factoid questions like "how many X in protein Y", "what drug interacts with Z", "what gene causes disease W", or "translate this sequence". These questions benefit from database lookups (UniProt, PubMed, ChEMBL, ClinVar, GWAS Catalog, etc.) rather than answering from memory alone. When in doubt about a scientific fact, USE THIS SKILL to verify against real databases.
