Functioni

Plays a key role in the sexual differentiation of germ cells by promoting the male fate but suppressing the female fate. Represses the female fate pathways by suppressing meiosis, which in turn results in the promotion of the male fate. Maintains the suppression of meiosis by preventing STRA8 expression, which is required for premeiotic DNA replication, after CYP26B1 is decreased. Regulates the localization of the CCR4-NOT deadenylation complex to P-bodies and plays a role in recruiting the complex to trigger the degradation of mRNAs involved in meiosis. Required for the maintenance of the spermatogonial stem cell population. Not essential for the assembly of P-bodies but is required for the maintenance of their normal state.5 Publications

Disruption phenotypei

Mice show a gradual loss of the germ cell population within a few cycles of spermatogenesis which is caused by the depletion of spermatogonial stem cells that produce differentiating spermatogenic cells.1 Publication

Expressioni

Tissue specificityi

Predominantly expressed in male germ cells. Expressed in self-renewing spermatogonial stem cells and developing gonads.2 Publications

Developmental stagei

First detectable at E13.5 in the male gonocytes, levels increase until about E16.5 and then slightly decrease by E17.5 (at protein level). Expression is maintained in all male gonocytes during embryogenesis, but becomes confined to a small population of the spermatogonia after birth.2 Publications
