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.
