s containing one or more FKBP12 domains. It is used in pharmacology to act as a mediator in the formation of FK506 dimer. FK506 binding proteins (FKBPs) do not normally form dimers but can be caused to dimerize in the presence of FK1012. Genetically engineered proteins based on FKBPs can be used to manipulate protein localization, signaling pathways and protein activation.
