Transforming growth factor beta (TGFβ) receptors are
heterodimeric.[1] The number of characterized ligands in the TGFβ superfamily far exceeds the number of known receptors, suggesting the promiscuity that exists between the ligand
and receptor interactions.
end-stage renal disease. Recent developments have found that, using certain types of protein antagonists against TGFβ receptors, can halt and in some cases reverse the effects of renal fibrosis.[citation needed

Three TGFβ superfamily receptors specific for TGFβ, the TGFβ receptors, can be distinguished by their structural and functional properties.
