The TGFβ (transforming growth factor β) superfamily proteins are pleiotropic cytokines that regulate a diverse range of cellular processes, including proliferation, differentiation, migration, adhesion and death.  The TGFβ superfamily elicits 4 signaling pathways: TGFβ, Bone Morphogenic Protein (BMP), Activin, and Nodal.  Each pathway signals through a heteromeric receptor complex composed of at least two type-I and two type-II transmembrane receptors containing cytoplasmic serine/threonine kinase domains. These receptors are distinguished by the presence of a glycine/serine-rich juxta-membrane domain found only in the type I receptors. Either type receptor may initially bind ligand, followed by the recruitment of an alternate-type receptor counterpart to form a signal-activating complex. AMHR2 (Anti-Müllerian hormone type 2 receptor), also known as MRII and MISRII, is a type II receptor that forms a heteromeric complex with various type I TGFBRs to mediate AMH (anti-Müllerian hormone) or MIS (Müllerian inhibiting substance) signaling. AMH/MIS, in addition to testosterone, plays a critical role in male sex differentiation. AMH and testosterone are produced in the testes by different cells and show different effects. Testosterone promotes the development of male genitalia, while the binding of AMH/MIS to AMHR2 prevents the development of the mullerian ducts into uterus and Fallopian tubes. Mutations in the AMHR2 are associated with persistent Müllerian duct syndrome type 2 (PMDS2). AMHR2 may suppress tumorigenesis in testes.
