**Background of TINF2 Recombinant Protein**
TINF2 (TERF1-interacting nuclear factor 2) is a critical component of the shelterin complex, a telomere-specific protein complex essential for maintaining genomic stability by protecting chromosome ends from DNA damage responses and regulating telomere length. Encoded by the *TINF2* gene located on human chromosome 14q32. the protein interacts directly with TERF1 (TRF1), TERF2 (TRF2), and POT1. bridging double-stranded and single-stranded telomeric DNA-binding proteins within the shelterin assembly.
Mutations in *TINF2* are linked to dyskeratosis congenita (DC) and other telomere biology disorders (TBDs), characterized by accelerated telomere shortening, bone marrow failure, and cancer predisposition. These findings highlight TINF2's non-redundant role in telomere homeostasis. Recombinant TINF2 protein, produced via heterologous expression systems (e.g., *E. coli* or mammalian cells), enables mechanistic studies of shelterin assembly, telomere replication, and disease-associated variants.
Researchers employ TINF2 recombinant proteins to investigate its structural domains, post-translational modifications, and interactions with telomeric DNA or shelterin partners. Such studies are vital for understanding how pathogenic mutations disrupt telomere protection and contribute to aging-related or cancerous phenotypes. Additionally, recombinant TINF2 serves as a tool for screening small molecules targeting telomere maintenance pathways, offering potential therapeutic avenues for TBDs or cancers reliant on telomere elongation.
In summary, TINF2 recombinant protein provides a versatile platform to dissect telomere biology, disease mechanisms, and therapeutic strategies, bridging molecular insights with clinical applications.
