**Background of TSGA14 (Testis-Specific Gene Antigen 14) Protein**
TSGA14. a protein encoded by the *TSGA14* gene, is predominantly expressed in the testis and plays a critical role in spermatogenesis. It is characterized by a conserved PHD (Plant Homeodomain) zinc finger motif, which mediates protein-protein interactions and chromatin remodeling, and a coiled-coil domain involved in oligomerization. Studies suggest TSGA14 participates in chromosomal condensation, acrosome formation, and cell division during sperm development. Notably, its expression extends beyond the male reproductive system, with aberrant levels observed in various cancers, including breast, prostate, and gliomas, indicating potential dual roles in both reproduction and oncogenesis.
In cancer biology, TSGA14 is proposed to act as a tumor suppressor by inhibiting hypoxia-inducible factor (HIF)-mediated pathways, thereby reducing angiogenesis and tumor growth. However, conflicting reports highlight context-dependent roles, as its overexpression in some malignancies correlates with aggressive phenotypes. Additionally, TSGA14 interacts with proteins involved in DNA repair (e.g., RAD51) and apoptotic regulation, suggesting broader functional versatility.
Emerging evidence links TSGA14 mutations or dysregulation to infertility and cancer progression, positioning it as a biomarker or therapeutic target. Ongoing research aims to elucidate its molecular mechanisms and tissue-specific functions, bridging reproductive biology and cancer research. Animal models with *TSGA14* knockout exhibit impaired sperm maturation, reinforcing its indispensability in fertility. Further exploration of its dual roles may unlock clinical applications in both andrology and oncology.
