PRR19 (Proline-Rich Protein 19) is a human protein encoded by the PRR19 gene, located on chromosome 19q13.33. It is evolutionarily conserved and characterized by a proline-rich N-terminal region and a BRCA1 C-terminal (BRCT) domain at its C-terminus, suggesting roles in protein-protein interactions and DNA damage response. Studies link PRR19 to homologous recombination repair (HRR), a critical pathway for maintaining genomic stability by repairing DNA double-strand breaks. Research in mouse models shows PRR19 interacts with BRCA1 and other HRR components, co-localizing with RAD51 and γH2AX at DNA damage sites. Its deficiency disrupts HRR efficiency, leading to chromosomal aberrations and increased sensitivity to ionizing radiation.
PRR19 is highly expressed in germ cells, particularly during spermatogenesis, implicating a role in meiosis. Aberrant expression is observed in cancers, with elevated levels correlating with poor prognosis in some malignancies (e.g., lung adenocarcinoma), though contradictory findings exist in other contexts. Recombinant human PRR19 protein, typically produced via bacterial or mammalian expression systems, enables functional studies of its interactions, post-translational modifications, and mechanistic contributions to DNA repair. Structural analyses highlight its intrinsically disordered N-terminal domain and BRCA1-binding capacity via the BRCT domain. While its precise regulatory mechanisms remain unclear, PRR19 is emerging as a potential biomarker or therapeutic target in cancer and reproductive biology. Further research is needed to delineate its molecular partners and signaling pathways.
