Background

  • Function

    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 (PubMed:15608617, PubMed:16166375, PubMed:20655466, PubMed:28216226, PubMed:9326950, PubMed:9326951, PubMed:9476899). 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 (PubMed:16166375, PubMed:20655466). Component of the shelterin complex (telosome) that is involved in the regulation of telomere length and protection (PubMed:16166375). 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 (PubMed:16166375). 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 (PubMed:20655466). Required both to recruit DCLRE1B/Apollo to telomeres and activate the exonuclease activity of DCLRE1B/Apollo (PubMed:20655466, PubMed:28216226). Preferentially binds to positive supercoiled DNA (PubMed:15608617, PubMed:20655466). 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 (PubMed:20655466). Recruits TERF2IP/RAP1 to telomeres, thereby participating in to repressing homology-directed repair (HDR), which can affect telomere length (By similarity)

  • Subcellular Localization

    Nucleus; Chromosome, telomere

  • Expression


    Tissue_specificity:It is widely distributed. It is highly expressed in the spleen, thymus, prostate, uterus, testes, small intestine, colon, and peripheral blood leukocytes.

  • Isoforms & Post-Translational Modification

    Q15554 has 2 isomers: Q15554-3: 59594 Da (predicted); Q15554-4: 32298 Da (predicted).
    Phosphorylated upon DNA damage, most probably by ATM. Phosphorylated TERF2 is not bound to telomeric DNA, and rapidly localizes to damage sites;Methylated by PRMT1 at multiple arginines within the N-terminal Arg-rich region. Methylation may control association with telomeres

  • Subunit

    Homodimer (PubMed:15608617). Component of the shelterin complex (telosome) composed of TERF1, TERF2, TINF2, TERF2IP/RAP1, ACD and POT1 (PubMed:15316005, PubMed:15383534, PubMed:15608617, PubMed:18202258). Interacts with NBN; interaction takes place with unphosphorylated NBN during G1 phase and prevents to prevent ATM activation and non-homologous end joining repair (PubMed:10888888, PubMed:28216226). Interacts with SLX4/BTBD12 (PubMed:19596235). Interacts with DCLRE1B/Apollo and TERF2IP/RAP1; the interaction is direct (PubMed:16606622, PubMed:16730175, PubMed:16730176, PubMed:18468965, PubMed:18593705, PubMed:20655466)
