Repeat amino acid sequences are important in protein structure, disorder, function and evolution. Repeats of some amino acids exist in proteomes across species.

This volume highlights:

• Which repeat sequences have pathogenic consequences and why?
• Repeats which lead to surface hydrophobic clusters and their importance.
• Role of aromatic amino acid clusters in protein-protein and protein-drug interactions.
• Cell-penetrating peptides and Elastin-like peptides.
• Unusual phenomenon of fluorescence observed with repeats of some non-aromatic amino acids.
• The use of residue cluster classes to represent protein structure and model structure-function relationships.
