🔬 Scientific Background

AlphaFold Integration

Spymot uses the AlphaFold Protein Structure Database 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
