## 🔬 Scientific Background

### AlphaFold Integration
Spymot uses the [AlphaFold Protein Structure Database](https://alphafold.ebi.ac.uk/) to assess 3D structural context:

- **pLDDT Scores**: Per-residue confidence from AlphaFold models
- **Threshold**: ≥70 pLDDT indicates reliable 3D structure
- **Coverage**: 200M+ protein structures from model organisms

### Confidence Scoring Integration
Spymot uses AlphaFold2 pLDDT scores to validate motif predictions:
- **pLDDT > 90**: Very high confidence - motif likely structured and functional
- **pLDDT 70-90**: Confident - motif probably functional with good structure
- **pLDDT 50-70**: Low confidence - motif may be disordered but still functional
- **pLDDT < 50**: Very low confidence - motif prediction uncertain

### Short Linear Motifs (SLiMs) in Cancer Biology
Short Linear Motifs are 3-10 amino acid sequences that mediate crucial protein functions:

#### Functional Classes
1. **Degrons**: Target proteins for degradation (APC/C, SCF complexes)
2. **Kinase Sites**: Phosphorylation targets (CDK, ATM/ATR, PKA)
3. **Interaction Motifs**: Protein binding sites (SH2, SH3, PDZ, 14-3-3)
4. **Localization Signals**: Subcellular targeting (NLS, NES, organellar signals)

#### Cancer Relevance
- **Tumor Suppressors**: p53 contains 15+ regulatory motifs
- **Oncoproteins**: Myc, β-catenin rely on motifs for function/regulation
- **Drug Targets**: Kinase sites are primary targets for cancer therapy
- **Biomarkers**: Motif mutations predict treatment response
