Furthermore, we found that Nek7 overexpression could enhance TRF1 protein expression (XREF_FIG), suggesting that Nek7 may regulate TRF1 expression either at the transcription or posttranscriptional levels.|We show that Nek7 phosphorylates TRF1 at Ser114 and in turn maintains stability of the shelterin complex at telomeres.

pmid sentence
Using KR-TRF2 to induce telomeric DNA damage, we found that TRF1 degradation was also exacerbated when ATM was inhibited after damage induction (55.2% of mock treated cells) (XREF_FIG), indicating that the ATM signal pathway is required for Nek7 mediated TRF1 stabilization.|We show that Nek7 phosphorylates TRF1 at Ser114 and in turn maintains stability of the shelterin complex at telomeres.

pmid sentence
Mechanistically, Nek7 interacts with and phosphorylates TRF1 on Ser114, which prevents TRF1 from binding to Fbx4, an Skp1-Cul1-F box E3 ligase subunit, thereby alleviating proteasomal degradation of TRF1, leading to a stable association of TRF1 with Tin2 to form a shelterin complex.

pmid sentence
Regulation of telomeric repeat binding factor 1 binding to telomeres by casein kinase 2-mediated phosphorylation. Mapping of the ck2 target site identified threonine 122 as a substrate in trf1. A threonine to alanine change at this position led to a diminished dna binding due to reduced dimerization of trf1.

pmid sentence
The shelterin complex has six proteins, containing TRF1, TRF2, POT1, RAP1, TIN2, and TPP1. The shelterin complex is localized to the chromosome end and protects telomeric DNA (Palm and de Lange, 2008). The TTM complex acts as a “linker” and bridges the LINC and shelterin complexes together. The connection between TTM and shelterin complexes is well-known, which is mediated by TERB1 and TRF1

Taken together these observations suggest that NCAPH2 promotes telomere stability, possibly through a direct interaction with the TRF1 shelterin component, and prevents telomere dysfunction resulting from impaired DNA replication.
