Cripto_Frl-1_Cryptic (CFC)
CFC domain is one half of the membrane protein Cripto, a protein overexpressed in many tumors and structurally similar to the C-terminal extracellular portions of Jagged 1 and Jagged 2. CFC is approx 40-residues long, compacted by three internal disulphide bridges, and binds Alk4 via a hydrophobic patch. CFC is structurally homologous to the VWFC-like domain.
