C. elegans NANOS-3 (NOS-3) physically interacts with FBF RNA-binding protein, as demonstrated by yeast two-hybrid and in vitro binding assays. This complex is proposed to repress fem-3 mRNA to control the sperm-oocyte switch. Loss of nos-3 (deletion mutant) causes defects in the hermaphrodite sperm-oocyte switch and germ-line death that does not require the apoptotic protease CED-3. |

Mouse NANOS3 interacts with the RNA-binding protein Pumilio2, forming a conserved translational repressor complex. In prepuberal testis, NANOS3 upregulation causes accumulation of spermatogonial cells in G1 phase, indicating it delays cell cycle progression. Expression is downregulated by retinoic acid (a differentiation factor), consistent with a role in maintaining undifferentiated spermatogonia. |

NANOS3 maintains the germ cell lineage in mouse embryos by suppressing both Bax-dependent and Bax-independent apoptotic pathways. In Nanos3-null embryos, migrating primordial germ cells (PGCs) undergo apoptosis. Double knockout of Nanos3 and Bax only partially rescued PGC apoptosis, demonstrating that NANOS3 suppresses a Bax-independent apoptotic pathway in addition to the Bax-dependent pathway. |

NANOS3-EGFP fusion protein co-localizes predominantly with TIAL1 (TIAR) and phosphorylated eIF2α (markers of stress granules) in primordial germ cells, while a fraction co-localizes with DCP1A (a processing body marker). NANOS3-EGFP does not co-localize with Tudor domain-containing protein 1 (intermitochondrial cement marker) in spermatogenic cells. The transgene fully rescues the sterile phenotype of Nanos3 homozygous mutants, confirming functional equivalency. |

The Nanos3 3'UTR is required for germ cell-specific expression of NANOS3 in mouse embryos. Although Nanos3 is transcribed in both germ cells and somatic cells, the 3'UTR mediates mRNA destabilization in somatic cells, restricting protein expression to the germline. Even under strong ubiquitous CAG promoter-driven transcription, addition of the Nanos3 3'UTR sequence to an exogenous gene was sufficient to restrict protein expression to germ cells. |

NANOS3 is expressed in human germ cell nuclei where it co-localizes with chromosomal DNA during mitosis/meiosis. Reduced NANOS3 expression (via morpholinos or shRNA) in human embryonic stem cell-derived germ cells causes a reduction in germ cell numbers and decreased expression of germ cell-intrinsic genes required for maintenance of pluripotency and meiotic initiation and progression. |

A homozygous p.Glu120Lys mutation in NANOS3, located within the second C2HC motif of the zinc finger domain, impairs NANOS3's capacity to prevent apoptosis as shown by in vitro flow cytometry and confocal microscopy apoptosis assays. In silico modelling suggests this mutation destabilizes protein-RNA interaction. |

NANOS3 associates with the CCR4-NOT deadenylation complex via a direct interaction with CNOT8, in contrast to NANOS2 which interacts with CNOT1. This differential interaction with CCR4-NOT components underlies the molecular basis for functional redundancy and differences between NANOS2 and NANOS3 in male germ cells. |

Human NANOS3 promotes epithelial-mesenchymal transition (EMT) in lung cancer cells by repressing E-cadherin at the transcriptional level and upregulating vimentin post-transcriptionally. NANOS3 binds vimentin mRNAs and regulates the length of their poly(A) tail. NANOS3 also protects vimentin mRNA from microRNA-mediated repression. |

DND1 interacts with NANOS2 or NANOS3, and these complexes play a vital role in male embryonic germ cells. Double mutants for Dnd1 and Nanos2 or Nanos3 show synergistic increases in testicular teratoma incidence, placing DND1 in the same pathway as NANOS3 for suppression of teratoma formation from PGCs in the 129 genetic background. |

NANOS3 fails to bind CNOT1 (an N-terminal interactor of NANOS2), and its ability to recruit DND1 is poor due to differences in the zinc-finger structure compared to NANOS2. Conditional double knockout of Nanos2 and Nanos3 leads to rapid loss of germ cells. These molecular differences explain why NANOS3 cannot rescue NANOS2 function despite being upregulated in Nanos2-null conditions. |

Mice heterozygous for both Nanos3 and Ptbp1 (Nanos3+/-;Ptbp1+/-) show abnormal spermatogenesis resembling germ cell-specific Ptbp1 KO, while single heterozygotes are normal, demonstrating a genetic interaction between PTBP1 and NANOS3 in spermatogonium homeostasis. |

NANOS3 in complex with PUM1 causes 3'UTR-mediated post-transcriptional repression of FOXM1 mRNA, which encodes a transcription factor critical for G2/M phase transition. NANOS3 specifically influences the G2/M cell cycle phase transition (distinct from NANOS1 which affects G1/S), identified in a human primordial germ cell model (TCam-2 cells). |

Conditional deletion of Nanos3 at a later embryonic stage (after PGC specification) results in reduction of spermatogonial progenitors postnatally due to premature differentiation. This premature differentiation causes seminiferous stage disagreement and disrupts the spermatogenic epithelial cycle. NANOS3 blocks the retinoic acid (RA) signaling pathway to suppress premature spermatogonial differentiation. |

DND1 and NANOS3 form a ribonucleoprotein complex that specifically recognizes an AUGAAUU heptanucleotide motif (N3-DRE) in 3'UTRs of target mRNAs including CDK1. mRNAs with N3-DREs are aberrantly upregulated in DND1- or NANOS3-deficient germ cells. The N3-DRE is essential for Cdk1 repression in mouse PGCs in vivo. A 1.7-Å crystal structure of the ternary DND1-NANOS3-CDK1 N3-DRE RNA complex reveals a continuous RNA-binding surface conferring high-affinity sequence-specific recognition. NANOS3 has no intrinsic sequence-specificity alone but jointly with DND1 builds a high-information-content recognition motif. |

DND1 and NANOS3 form a complex in human PGC-like cells (hPGCLCs) that restricts PGC specification. DND1 facilitates the binding of NANOS3 to hPGCLC-related mRNAs. SOX4 mRNA is a key downstream target of the DND1-NANOS3 complex; the complex functions in processing bodies (P-bodies) to repress SOX4 mRNA translation. NANOS3 mediates the interaction between DND1 and the translational repressor 4E-T. |

In zebrafish, Nanos3 and Dead end1 (Dnd1) form a complex that activates translation of both nanos3 and dead end1 RNAs, establishing a positive feedback loop. Nanos3 acts as a translational activator (not repressor) in this context by interacting with an eIF3 complex protein, promoting translation and maintaining specific RNAs at the periphery of phase-separated germ granules. Disrupting the physical interaction between Nanos3 and Dead end1 leads to transdifferentiation of germ cells into somatic lineages. |
