This is an alignment of the hydrophilic cysteine-rich ligand-binding domains, Both receptor types, (type I and II) posses a 9 amino acid cysteine box, with the the consensus CCX{4-5}CN. The t ...	This Pfam entry consists of both TGF-beta receptor types. This is an alignment of the hydrophilic cysteine-rich ligand-binding domains, Both receptor types, (type I and II) posses a 9 amino acid cysteine box, with the the consensus CCX{4-5}CN. The type I receptors also possess 7 extracellular residues preceding the cysteine box.	Domain
