title: Engagement of bone morphogenetic protein type IB receptor and Smad1 signaling by anti-Müllerian hormone and its type II receptor.
abstract: Anti-Müllerian hormone induces the regression of fetal Müllerian ducts and inhibits the transcription of gonadal steroidogenic enzymes. It belongs to the transforming growth factor-beta family whose members signal through a pair of serine/threonine kinase receptors and Smad effectors. Only the anti-Müllerian hormone type II receptor has been identified. Our goal was to determine whether anti-Müllerian hormone could share a type I receptor with another family member. Co-immunoprecipitation of known type I receptors with anti-Müllerian hormone type II receptor clearly showed that the bone morphogenetic protein type IB receptor was the only cloned type I receptor interacting in a ligand-dependent manner with this type II receptor. Anti-Müllerian hormone also activates the bone morphogenetic protein-specific Smad1 pathway and the XVent2 reporter gene, an anti-Müllerian hormone type II receptor-dependent effect abrogated by a dominant negative version of bone morphogenetic protein type IB receptor. Reverse amplification experiments showed that bone morphogenetic protein type IB receptor is co-expressed with anti-Müllerian hormone type II receptor in most anti-Müllerian hormone target tissues. Our data support a model in which a ligand, anti-Müllerian hormone, gains access to a shared type I receptor and Smad1 system through a highly restricted type II receptor.
