Goals

• Predict specificity of peptide recognition domain from the primary amino acid sequence.
• Analyze PDZ, WW and then SH3 domains

Strategy

Status

• [wiki:/Log Status Log]

Tasks

1. Learn SVN, Brain code (ResidueResidueCorrelation)

2. Literature review related to domain specificity (background activity)

3. Run ResidueResidue correlation analysis on PDZ domain data: 1-1 version + try others e.g. 1-2 (Requires: PDZ profiles from Gary)

4. Try different multiple sequence alignment algorithms (MSA) on the PDZ domain sequences to see if they affect the correlation results.
5. Implement new feature: amino acid groups (learn amino acid groups) + run on PDZ data
6. Think about new PDZ domain features that can be used for prediction.

Ideas

• Use of structural data (PDZ domain structures) (may require homology modeling)
• Use of machine learning methods (SVM for classification and boosting decision tree for interpretable learning model)
• Analysis of correlation within domain and peptide (inter-residue correlation) maybe correspondence analysis
