| + | [https://www.uniprot.org/uniprot/MIS_HUMAN MIS_HUMAN] Plays an important role in several reproductive functions. Induces Muellerian duct regression during male fetal sexual differentiation (PubMed:3754790, PubMed:34155118, PubMed:8469238). Also plays a role in Leydig cell differentiation and function (By similarity). In female acts as a negative regulator of the primordial to primary follicle transition and decreases FSH sensitivity of growing follicles (PubMed:14742691). AMH signals by binding to a specific type-II receptor, AMHR2, that heterodimerizes with type-I receptors (ACVR1 and BMPR1A), and recruiting SMAD proteins that are translocated to the nucleus to regulate target gene expression (PubMed:20861221, PubMed:34155118).[UniProtKB:P27106]<ref>PMID:14742691</ref> <ref>PMID:20861221</ref> <ref>PMID:34155118</ref> <ref>PMID:3754790</ref> <ref>PMID:8469238</ref> | ||

| + | Anti-Mullerian hormone (AMH), or Mullerian-inhibiting substance, is a protein hormone that promotes Mullerian duct regression during male fetal sexual differentiation and regulation of folliculogenesis in women. AMH is a member of the transforming growth factor beta (TGF-beta) family, which has evolved to signal through its own dedicated type II receptor, AMH receptor type II (AMHR2). Structures of other TGF-beta family members have revealed how ligands infer specificity for their cognate receptors; however, it is unknown how AMH binds AMHR2 at the molecular level. Therefore, in this study, we solved the X-ray crystal structure of AMH bound to the extracellular domain of AMHR2 to a resolution of 2.6A. The structure reveals that while AMH binds AMHR2 in a similar location to Activin and BMP ligand binding to their type II receptors, differences in both AMH and AMHR2 account for a highly specific interaction. Furthermore, using an AMH responsive cell-based luciferase assay, we show that a conformation in finger 1 of AMHR2 and a salt bridge formed by K534 on AMH and D81/E84 of AMHR2 are key to the AMH/AMHR2 interaction. Overall, our study highlights how AMH engages AMHR2 using a modified paradigm of receptor binding facilitated by modifications to the three-finger toxin fold of AMHR2. Furthermore, understanding these elements contributing to the specificity of binding will help in the design of agonists or antagonists or the selection of antibody therapies. | ||
