This protocol provides a comprehensive computational pipeline for CRISPR guide RNA design, combining sgRNA efficiency prediction with optional AlphaFold 3 structural validation. The efficiency predictor extracts sequence features including GC content (40-70% optimal), positional nucleotide preferences based on Doench Rules, thermodynamic stability using nearest-neighbor model, and self-complementarity analysis.

Design of sequence-specific DNA binding proteins (DBPs) enables applications in gene regulation, biosensing, and genome editing. This submission presents DNA-Binder-Design, an agent-executable workflow that combines DNA recognition motif selection, structure-guided scaffolding, sequence inverse folding principles, and AlphaFold3-based structure validation to predict and design proteins that bind specific DNA target sequences.
