The Protein Common Interface Database (ProtCID) organizes PDB-wide structural evidence about protein interfaces, domain-domain contacts, peptide interactions, and ligand or nucleic-acid interactions. It clusters recurring interfaces across homologous proteins so that structurally repeated contacts can be examined as candidate biologically relevant interactions.
ProtCID supports search by PDB identifiers, Pfam terms, UniProt accessions, and
sequence input, and it also exposes browse and help pages for interpreting common
interface clusters. The spoke graph remains attached here as a propagated
downstream product because SPOKE incorporates ProtCID structural interaction data
as one upstream source among many.
