Telomeric Repeat binding Factor or TTAGGG Repeat binding Factor, central (dimerization) domain Homology; TRFH. Telomeres are protein/DNA complexes that make up the physical ends of eukaryotic linear chromosomes and are essential for chromosome stability, protecting the chromosome ends from degradation and end-to-end fusion. Proteins TRF1, TRF2 and Taz1 bind telomeric DNA and are also involved in recruiting interacting proteins, TIN2, and Rap1, to the telomeres. It has also been demonstrated that PARP1 associates with TRF2 and is capable of poly(ADP-ribosyl)ation of TRF2, which affects binding of TRF2 to telomeric DNA. TRF1, TRF2 and Taz1 proteins contain three functional domains: an N-terminal acidic domain, a central TRF-specific/dimerization domain, and a C-terminal DNA binding domain with a single Myb-like repeat. Homodimerization, a prerequisite to DNA binding, results in the juxtaposition of two Myb DNA binding domains.

Telomere repeat binding factor-like DNA-binding domains of the SANT/myb-like family; Human telomere repeat binding factors, TRF1 and TRF2, function as part of the 6 component shelterin complex. TRF2 binds DNA and recruits RAP1 (via binding to the RAP1 protein c-terminal (RCT)) and TIN2 in the protection of telomeres from DNA repair machinery. Metazoan shelterin consists of 3 DNA binding proteins (TRF2, TRF1, and POT1) and 3 recruited proteins that bind to one or more of these DNA-binding proteins (RAP1, TIN2, TPP1). Schizosaccharomyces pombe TAZ1 is an orthlog and binds RAP1. Human TRF1 and TRF2 bind double-stranded DNA. hTRF2 consists of a basic N-terminus, a TRF homology domain, the RAP1 binding motif (RBM), the TIN2 binding motif (TBM) and a myb-like DNA binding domain, SANT, named after 'SWI3, ADA2, N-CoR and TFIIIB', several factors that share this domain. Tandem copies of the domain bind telomeric DNA tandem repeats as part of the capping complex. The single myb-like domain of TRF-type proteins is similar to the tandem myb_like domains found in yeast RAP1.

Telomere repeat binding factor (TRF); Telomere repeat binding factor (TRF) family proteins are important for the regulation of telomere stability. The two related human TRF proteins hTRF1 and hTRF2 form homodimers and bind directly to telomeric TTAGGG repeats via the myb DNA binding domain pfam00249 at the carboxy terminus. TRF1 is implicated in telomere length regulation and TRF2 in telomere protection. Other telomere complex associated proteins are recruited through their interaction with either TRF1 or TRF2. The fission yeast protein Taz1p (telomere-associated in Schizosaccharomyces pombe) has similarity to both hTRF1 and hTRF2 and may perform the dual functions of TRF1 and TRF2 at fission yeast telomeres. This domain is composed of multiple alpha helices arranged in a solenoid conformation similar to TPR repeats. The fungal members have now also been found to carry two double strand telomeric repeat binding factors.
