Interactions available from major taxonomies (corrected)

Taxons of the protein interactors have been corrected to correspond to the taxon provided in the protein sequence record regardless of the taxon listed in the interaction record. See PMID 18823568 for details.

Summary of mapping interaction records to RIGs (redundant interaction groups)

Source: Interaction data source. Total records: Total number of interaction records found in source. Protein-only interactors:Total number of interactions involving only protein interactors. PPI assigned to RIGID: Number of interactions where all protein interactors were assigned to a ROG. Percentage of column 3 is shown. Unique interactions: Number of unique protein interactions and complexes (RIGID's) found in the data source (also expressed as a percentage of column 4). For a description of the term RIGs, see README_MITAB2.6_for_iRefIndex#Understanding_the_iRefIndex_MITAB_format and the original paper PMID 18823568.

Assignment of protein interactors to ROGs (redundant object group)

Source: Interaction data source (see methods). Protein interactors: Total number of interactors found in all interaction records. Assigned: Number of proteins assigned unambiguously to a ROG. Assignments listed in columns 5 and 6 are not included here. %: Column 3 expressed as a percentage of column 2. Arbitrary: Total number of ROG assignments that were ambiguous and resolved with an arbitrary method (see ROG scores with 'L'). Matching sequence: Total number of assignments made where a sequence in the interaction record matched a known sequence. Unassigned:Total number of protein interactors that could not be assigned to a ROG. Unique: Total number of unique proteins (ROG's). For a description of the term ROGs, see README_MITAB2.6_for_iRefIndex#Understanding_the_iRefIndex_MITAB_format and the original paper PMID 18823568.
