AliasesProtein Complex Database with complex quality index
DescriptionPCDq is a human protein complex database with quality check index (QCI), which describes evidence levels as subunits (protein members) of the protein complex. In total, 1,319 human protein complexes were firstly predicted by finding densely connected regions with cluster properties in the PPI network integrated from six PPI data (BIND, DIP, MINT, HPRD, IntAct, and GNP_Y2H). Then they were curated with the literature so that PCDq consists of both known and predicted complexes/subunits. The evidence level for each subunit were also annotated and summarized to a quality check index (QCI) for each protein complex. PCDq can also show the complicated PPI sub-networks in a simple, editable graphical view "PPI-Map".
