背景信息

**Background of TEN1 Recombinant Protein**

The TEN1 (Telomeric Nuclear Protein 1) recombinant protein is a critical component of the mammalian CST (CTC1-STN1-TEN1) complex, which plays essential roles in telomere maintenance and genome stability. Telomeres, the protective caps at chromosome ends, prevent degradation and fusion by shielding terminal DNA. The CST complex, structurally and functionally analogous to the yeast Cdc13-Stn1-Ten1 complex, coordinates telomere replication and repair, particularly during lagging-strand synthesis. TEN1 interacts with STN1 and CTC1 to stabilize the G-rich telomeric single-stranded DNA (ssDNA), ensuring proper replication fork progression and resolving replication stress.

Recombinant TEN1 is produced using heterologous expression systems (e.g., *E. coli* or mammalian cells*) to study its biochemical properties, DNA-binding activity, and interactions within the CST complex. Structurally, TEN1 contains an OB-fold domain, a conserved motif for ssDNA binding, facilitating its role in telomere protection. Dysregulation of TEN1 or CST function is linked to telomere disorders (e.g., *Coats plus syndrome*) and cancer, where aberrant telomere elongation or shortening drives genomic instability.

Research applications include *in vitro* assays to dissect telomere replication mechanisms, drug screening for telomere-targeted therapies, and structural studies (e.g., cryo-EM) to resolve CST-DNA interaction dynamics. TEN1 recombinant protein also aids in modeling diseases caused by CST mutations and exploring therapeutic strategies to counteract telomere dysfunction in aging and cancer. Its production ensures high purity and activity, enabling precise mechanistic studies critical for advancing telomere biology and translational medicine.
