In differentiating Sertoli cells of the testis, the Amh gene is transcribed to yield mRNA and the mRNA is translated to yield Amh protein (Arango et al. 1999, Li et al. 2014). Sox9, Nr5a1 (SF1), and Gata4 bind the promoter of the Amh gene and activate transcription (Arango et al. 1999, Li et al. 2014).
