PPI view   Protein-Protein, Protein-Complex and Complex-Complex Interaction Viewer with Integrative Annotation   [ Help for PCDq ]
PCDq is a human protein complex database with quality index, which tells us the evidence level as members of the protein complex. We predicted human protein complexes from integrated PPI network data by finding densely connected regions with their cluster properties in the PPI network. We annotated the predicted complexes with our defined procedures by human curators that confirm the existence of the complex actually available in references. We integrated data entities such as protein function, localization, structure, expression profile, gene locus, and binary interactions among complex member proteins and complex outside adjacent proteins.
