^aSome IDPs can bind to different partners. ^b# of residues or binding residues in IDPs refer to all residues or all binding residues regardless if they are in structured, unstructured, or unannotated regions. ^c# of helical or sheet residues in IDRs

Please note that IDPs may contain both structured regions and IDRs as well as un-annotated regions
