Engagement of bone morphogenetic protein type IB receptor and Smad1 signaling by anti-Müllerian hormone and its type II receptor.

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.
