PCRPi-DB

PCRPi-DB annotates hot spots within protein interfaces, identifying residues that contribute disproportionately to total binding energy to support analysis of protein–protein interactions and target selection in drug discovery and protein design.

Key Features:

• Annotation of Hot Spots: PCRPi-DB identifies and annotates small regions within protein interfaces that significantly contribute to total binding energy.
• Computational Methodology: The database applies an in-house computational method to predict and annotate functionally significant interfacial residues.

Scientific Applications:

• Drug Discovery: Pinpointing interface hot spots aids identification of potential therapeutic targets and design of molecules that disrupt or stabilize protein–protein interactions.
• Protein Design: Annotation of critical interfacial residues informs engineering of proteins with altered binding specificity or affinity.
• Protein Interaction Analysis: Mapping residues that dominate binding energy supports mechanistic studies of protein–protein recognition and complex stability.

Methodology:

The database uses an in-house computational method to predict and annotate hot-spot residues at protein interfaces.
