FKBP12 functions as a "guardian" for the type I receptors to prevent them from leaky signaling under sub-optimal ligand concentrations, thereby providing a molecular "gradient reader" for TGF-beta family morphogens.
Unphosphorylated T??RI forms complexes with the FK506-binding protein (FKBP12). Binding of the latter to the GS region of T??RI caps the T??RII phosphorylation sites, thus further stabilizing T??RI in its inactive conformation
