Abstract

Gonadal fate in mammals is determined during embryogenesis and is actively maintained in adulthood. This study shows that E3-SUMO ligase activity of TRIM28 is required for ovarian identity maintenance and testicular-specific gene repression in mouse adult ovary; in its absence, ovarian granulosa cells transdifferentiate to Sertoli cells.
