 510-560 2.18e-15

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.

'SWI3, ADA2, N-CoR and TFIIIB' DNA-binding domains. Tandem copies of the domain bind telomeric DNA tandem repeatsas part of the capping complex. Binding is sequence dependent for repeats which contain the G/C rich motif [C2-3 A (CA)1-6]. The domain is also found in regulatory transcriptional repressor complexes where it also binds DNA.
