APRIN (Androgen-induced Proliferation Inhibitor), also known as PDSS2 or Sister Chromatid Cohesion Regulatory Factor, is a nuclear protein encoded by the *PDSS2* gene in humans. Initially identified as an androgen-responsive gene in prostate cancer cells, APRIN plays a critical role in regulating sister chromatid cohesion and DNA repair processes. It is involved in maintaining genomic stability by facilitating homologous recombination repair during the S phase of the cell cycle. Structurally, APRIN contains coiled-coil domains that mediate protein-protein interactions, particularly with key DNA repair factors like BRCA2 and RAD51. forming complexes essential for error-free DNA damage resolution.
Research highlights APRIN's dual functionality: it stabilizes cohesion between replicated chromosomes and promotes the recruitment of repair machinery to double-strand breaks. Dysregulation of APRIN has been implicated in carcinogenesis, with reduced expression observed in certain cancers (e.g., breast, ovarian), correlating with genomic instability and poor prognosis. Conversely, its overexpression may contribute to therapy resistance by enhancing DNA repair efficiency. Recombinant human APRIN protein, typically produced via Escherichia coli or mammalian expression systems, is widely utilized to study its molecular mechanisms, screen for targeted inhibitors, or explore its potential as a biomarker. Current studies focus on elucidating its interactions within DNA repair networks and its therapeutic relevance in precision oncology.
