Mapping of domain-mediated protein-protein interaction by SPOT peptide assay

Identification of peptides mediating protein-protein interaction (PPI) is crucial for understanding the function of interlinked proteins in cellular processes and amino acid-associated diseases. Traditional PPI assays are laborious, involving the generation of many truncated proteins. SPOT peptide assay allows high-throughput detection of domains essential for PPI by synthesizing several hundred peptides on a cellulose membrane. Here, we present...
