Anti-Müllerian hormone type-2 receptor (AMHR2)

Target
AMHR2
Molecular classification
Receptor, Transforming growth factor beta (TGF-β) type II receptor family, Single-pass transmembrane protein
01

Overview

Anti-Müllerian hormone type-2 receptor (AMHR2) is a transmembrane serine/threonine kinase receptor belonging to the TGF-β receptor superfamily. It is the dedicated type II receptor for anti-Müllerian hormone (AMH) and is vital for male sexual differentiation by mediating regression of the Müllerian ducts in the developing embryo. AMHR2 is essential for proper gonadal development and also regulates follicle recruitment in the adult ovary. The receptor is characterized structurally by a three-finger toxin fold in its extracellular domain, conferring selectivity for AMH binding. Variations or dysfunction in this receptor are associated with sexual development disorders and certain reproductive cancers. Currently, AMHR2 is under investigation as a therapeutic and diagnostic target, especially in rare reproductive cancers and fertility-related conditions[1][2][3].

Mechanism of action

Agonists or antagonists would modulate AMH signaling by binding to AMHR2 and altering downstream SMAD pathway activation Therapeutic antibodies might block or mimic AMH binding to the receptor
