General annotation (Comments)

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. 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. Ref.5 Ref.9 Ref.22
Subunit structure	Homodimer. Component of the shelterin complex (telosome) composed of TERF1, TERF2, TINF2, TERF2IP/RAP1, ACD and POT1. Interacts with TERF2IP. Interacts with NBN. Interacts with SLX4/BTBD12. Interacts with DCLRE1B/Apollo and TERF2IP/RAP1; the interaction is direct. Ref.6 Ref.7 Ref.8 Ref.12 Ref.13 Ref.14 Ref.16 Ref.17 Ref.19 Ref.22 Ref.27 Ref.28
Subcellular location	Nucleus. Chromosome › telomere. Note: Colocalizes with telomeric DNA in interphase cells and is located at chromosome ends during metaphase. Ref.22
Tissue specificity	Ubiquitous. Highly expressed in spleen, thymus, prostate, uterus, testis, small intestine, colon and peripheral blood leukocytes.
Domain	The TRFH dimerization region mediates the interaction with DCLRE1B/Apollo but not TINF2. Ref.28 The HTH domain is an independent structural unit and mediates binding to telomeric DNA. Ref.28
Post-translational modification	Phosphorylated upon DNA damage, most probably by ATM. Phosphorylated TERF2 is not bound to telomeric DNA, and rapidly localizes to damage sites. Ref.10 Methylated by PRMT1 at multiple arginines within the N-terminal Arg-rich region. Methylation may control association with telomeres. Ref.20
Sequence similarities	Contains 1 HTH myb-type DNA-binding domain.
