Background: TMEFF1/Tomoregulin-1

TMEFF1 (Transmembrane protein with EGF-like and two Follistatin-like domains 1), also known as tomoregulin 1 is a type I transmembrane glycoprotein that contains two follistatin modules and an EGF domain in its extracellular domain, a transmembrane domain and a short cytoplasmic tail. The extracellular domain can be released as a soluble protein. TMEFF1 selectively regulates nodal but not activin signaling through direct binding to the nodal co-receptor, Cripto.
