NCOA3 and Infertility: Knockout mice of steroid receptor co-activator 3 (SRC-3), a member of p160 family, exhibit infertility [22], and those of nuclear receptor interacting protein 1 (Nrip1/RIP140) are also infertile due to the blockage of the oocyte release from the Graafian follicles by the ovulatory stimuli [23].
