Hot spots (HS), the small subset of interface residues that contribute disproportionately to binding free energy, are prime targets for drug design and the rational engineering of proteinโ€“protein interactions. Identifying them experimentally is costly and low-throughput; computational prediction from sequence alone offers a scalable alternative.

SpotONE is a machine-learning predictor built on Extremely Randomized Trees that classifies every residue in a submitted protein sequence as a hot spot or non-hot spot using sequence-derived features exclusively. No structural data is required, making it immediately applicable to any protein with a known sequence, and results are delivered directly to the user’s inbox.

How It Works

  1. Submit a FASTA file: One or more soluble protein sequences in standard single-letter code
  2. Model runs remotely: Sequence-only features are extracted and scored by the ET classifier
  3. Results by email: Per-residue HS / NS predictions delivered with interactive plots
