靶點詳情

  • 功能：
    Binds the telomeric double-stranded 5'-TTAGGG-3' repeat and plays a central role in telomere maintenance and protection against end-to-end fusion of chromosomes. In addition to its telomeric DNA-binding role, required to recruit a number of factors and enzymes required for telomere protection, including the shelterin complex, TERF2IP/RAP1 and DCLRE1B/Apollo. Component of the shelterin complex (telosome) that is involved in the regulation of telomere length and protection. Shelterin associates with arrays of double-stranded 5'-TTAGGG-3' 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. Together with DCLRE1B/Apollo, plays a key role in telomeric loop (T loop) formation by generating 3' single-stranded overhang at the leading end telomeres: T loops have been proposed to protect chromosome ends from degradation and repair. Required both to recruit DCLRE1B/Apollo to telomeres and activate the exonuclease activity of DCLRE1B/Apollo. Preferentially binds to positive supercoiled DNA. Together with DCLRE1B/Apollo, required to control the amount of DNA topoisomerase (TOP1, TOP2A and TOP2B) needed for telomere replication during fork passage and prevent aberrant telomere topology. Recruits TERF2IP/RAP1 to telomeres, thereby participating in to repressing homology-directed repair (HDR), which can affect telomere length.

    2. Selective inactivation of Terf2 in neural progenitors induced apoptosis, resulting in a complete loss of the brain structure. PMID: 28620865
    3. The authors propose that TRF2 masks and stabilizes the t-loop three-way junction, thereby protecting telomeres from detrimental deletions and PARP1 activation. PMID: 28805810
    4. TRF2, a component of shelterin, binds to core histones to protect chromosome ends from inappropriate DNA damage response and loss of telomeric DNA. The N-terminal Gly/Arg-rich domain (GAR domain) of TRF2 directly binds to the globular domain of core histones. PMID: 27514743
    5. Overexpressing TRF2-S and silencing FMRP promotes mRNA entry to axons and enhances axonal outgrowth and neurotransmitter release from presynaptic terminals. PMID: 26586091

    8. shelterin protein TIN2 can protect chromosome ends as a TRF2-tethered TIN2/TPP1/POT1 complex that lacks a physical connection to TRF1 PMID: 24469404
    9. We concluded that genomic instability resulting from loss of TRF2 expression provides biological advantages to the cancer stem cell population PMID: 23178498
    10. Conditional deletion of individual components of shelterin showed that TRF2 was required for the formation and/or maintenance of t-loops, whereas deletion of TRF1, Rap1, or the POT1 proteins (POT1a and POT1b) had no effect on the frequency of t-loop occurrence. PMID: 24120135
    11. TAF7L associates with TRF2 both in vitro and in testis, suggesting that TAF7L likely cooperates directly with TRF2 at promoters of a subset of postmeiotic genes to regulate spermiogenesis. PMID: 24082143
    12. Experiments in cells from knockout mice showed that uPAR controls the ubiquitin-proteasome system in VSMC & regulates doxorubicin-induced TRF2 ubiquitination and proteasomal degradation via this mechanism. PMID: 23172421
    13. the molecular properties of TRF2 that are both necessary and sufficient to protect chromosome ends in mouse embryonic fibroblasts: the data support a two-step mechanism for TRF2-mediated end protection PMID: 23389450
    14. TRF2 provides a crucial link between telomere function and ultraviolet-induced damage repair, whose alteration underlies genomic instability, cancer and aging. PMID: 16142233
    15. PARP1 associates with telomere repeat binding factor 2 (TRF2) and is capable of poly(ADP-ribosyl)ation of TRF2, which affects binding of TRF2 to telomeric DNA. PMID: 16436506
    16. with overexpressing the TRF2 telomere-binding protein, mice show short telomeres in the presence of telomerase activity, leading to premature aging and increased cancer PMID: 16582635
    17. TRF2 and POT1 act independently to repress two DNA damage response pathways; TRF2 represses ATM, whereas POT1 prevents activation of ATR PMID: 17687332
    18. The inactivation of TRF2ts at 37 degrees C was rapid and reversible, permitting induction of short periods (3-6 h) of telomere dysfunction in the G0, G1, and S/G2 phases of the cell cycle. PMID: 18451109
    19. These findings indicate a previously unnoticed role for TRF2 in the assembly of telomeric chromatin. PMID: 18971622
    20. the TRF2 telomeric protein has a role in telomere-associated diseases in mouse epidermal stem cells PMID: 19259387
