Target Data

Function Component of the shelterin complex (telosome) that is involved in the regulation of telomere length and protection. Shelterin associates with arrays of double-stranded TTAGGG repeats added by telomerase and protects chromosome ends; without its protective activity, telomeres are no longer hidden from the DNA damage surveillance and chromosome ends are inappropriately processed by DNA repair pathways. Plays a role in shelterin complex assembly. Isoform 1 may have additional role in tethering telomeres to the nuclear matrix.
Gene References into Functions
  1. The TIN2 plays an important role in maintaining the stable shelterin complex required for proper telomere end protection. PMID: 29160297
  2. We report ophthalmic findings in twins with Revesz syndrome due to a previously unreported mutation in TINF2 and propose that phenotypic and molecular overlaps between DKC spectrum disorders and pediatric retinal vasculopathies may reflect a shared pathophysiologic basis. PMID: 28095086
  3. demonstrate here the presence of a novel spliced isoform of TIN2 in chronic lymphocytic leukemia (CLL), related to deletion of exon 2 in the TIN2 gene PMID: 28575699
  4. data supports a mechanism whereby telomerase deficiency and subsequent shortened telomeres initiate a DNA damage response and create a pro-oxidant environment, especially in Dyskeratosis Congenita cells carrying TINF2 mutations PMID: 26859482
  5. telomerase elongates telomeres at a reduced frequency in TIN2-R282H heterozygous cells; this recruitment defect is further corroborated by examining the effect of this mutation on telomerase-telomere co-localization. PMID: 26230315
  6. Our findings identify TINF2 as a mutant telomere gene in familial pulmonary fibrosis and suggest that infertility may precede the presentation of pulmonary fibrosis in a small subset of adults with telomere syndromes PMID: 25539146
  7. A potential mitotic regulation of TIN2 by phosphorylation, is reported. PMID: 23977114
  8. results suggest a link between telomeric proteins (TIN2)and metabolic control, providing an additional mechanism by which telomeric proteins regulate cancer and aging PMID: 22885005
  9. Results suggests that the disruption of TIN2-TRF1 interaction may contribute to the severe dyskeratosis congenita phenotype observed in the context of the TIN2 truncation mutation. PMID: 21477109
  10. The positive correlation between telomere length in dyskeratosis congenital and percent of LINE-1 methylation was restricted to TINF2 mutations. PMID: 21981348
  11. Frameshift or nonsense mutations in TIN2 gene having very short telomeres are found in patients with dyskeratosis congenita. PMID: 21199492
  12. Siah2 acts as an E3 ligase to directly ubiquitylate TIN2 in vitro. PMID: 22064479
  13. These results demonstrate the important roles that Sp1 and NF-kappaB play in regulating the expression of the human telomere-binding protein TIN2. PMID: 21731707
  14. The presence of dysfunctional telomeres in chronic lymphocytic leukemia did not correlate with telomere shortening or chromatin marks deregulation but with a down-regulation of 2 shelterin genes: ACD and TINF2. PMID: 21355086
  15. TIN2 mutations in DC may compromise the telomere recruitment of telomerase, leading to telomere shortening and the associated pathogenesis. PMID: 21536674
  16. exon 6 of TINF2 natural mutations in 2/142 Japanese patients with acquired acquired bone marrow failure syndromes PMID: 20560964
  17. TINF2 mutation of shelterin complex is associated with dyskeratosis congenita. PMID: 20979174
  18. The expression of TINF2 may work to reduce the telomere length in precancerous lesions and offer new insight into the mechanism of carcinogenesis in gastric cancer. PMID: 20127252
  19. TIN2-anchored TPP1 plays a major role in the recruitment of telomerase to telomeres in human cells. PMID: 20404094
  20. Co-localises with the interstitial TTAGGG repeats in interstitial telomeres. PMID: 11938440
  21. Down-regulation of TRF1, TRF2 and TIN2 genes is important to maintain telomeric DNA for gastric cancers. PMID: 12530079
  22. TIN2 alters the conformation of TRF1, which favours a tertiary telomeric structure that hinders telomerase from gaining access to telomeres PMID: 12835755
  23. Partial knockdown of TIN2 by small hairpin RNA in a telomerase-positive cell line resulted in telomere elongation, which is typical of reduced TRF1 function. PMID: 15133513
  24. TIN2 mutants defective in binding of TRF1 or TRF2 induce a DNA damage response and destabilize TRF1 and TRF2 at telomeres in human cells. PMID: 15292264
  25. TIN2 binds TRF1 and TRF2 simultaneously and stabilizes the TRF2 complex on telomeres PMID: 15316005
  26. May be involved in multistep hepatocarcinogenesis by playing crucial role in telomere shortening. PMID: 15632001
  27. a novel extra-telomeric organization of TIN2 is associated with the control of cell proliferation; TIN2 is an important regulator of mammary epithelial differentiation PMID: 15741234
  28. coordinated interactions among TPP1, TIN2, TRF1, and TRF2 may ensure robust assembly of the telosome, telomere targeting of its subunits, and, ultimately, regulated telomere maintenance PMID: 16880378
  29. TINF2, a component of the shelterin telomere protection complex, is mutated in dyskeratosis congenita. PMID: 18252230
  30. Results suggest that distinct TIN2 complexes exist and that TIN2-15C-sensitive subcomplexes are particularly important for cell survival in the absence of functional p53. PMID: 18443218
  31. In a large series, TINF2 mutations account for approximately 11% of all patients with dyskeratosis congenita. PMID: 18669893
  32. conclude that a significant proportion of patients who underwent unrelated donor hematopoietic stem cell transplantation for severe aplastic anemia harbored mutations in TINF2 and may have had occult dyskeratosis congenita PMID: 19090550
  33. Our results suggest a dual role for TIN2 in mediating the function of the shelterin complex and tethering telomeres to the nuclear matrix. PMID: 19229133
