Rap1 Myb domain; The Rap1 Myb domain adopts a canonical three-helix bundle tertiary structure, with the second and third helices forming a helix-turn-helix variant motif. The function of this domain is unclear: it may either interact with DNA via an adaptor protein or it may be only involved in protein-protein interactions. : Pssm-ID: 286058 Cd Length: 65 Bit Score: 119.16 E-value: 2.31e-33

300-393 | 2.90e-21 | |||
C-terminal domain of RAP1 recruits proteins to telomeres; The RAP1 (repressor activator protein 1) C-terminal domain (RCT) mediates interactions with other proteins such as TRF2 (human), Rif1, Rif2, Sir3, Sir4 (Saccharomyces cerevisiae), and Taz1 (Schizosaccharomyces pombe) at telomeres and other loci. RAP1, identified in budding yeast as repressor/activator protein 1, is a well-conserved telomere binding protein, also found in fission yeast and mammals. In Saccharomyces cerevisiae, RAP1 directly binds DNA and is involved in transcriptional activation, gene silencing, as well as binding at numerous sites at each telemore, where it functions in telomere length regulation, telomeric position effect gene silencing and telomere end protection. Human RAP1 apparently does not bind telomeric DNA directly, but binds telomere repeat binding factor 2 (TRF2) via the RCT. RAP1 might act by suppressing nonhomologous end-joining. Yeast RAP1 has two myb-type DNA binding modules, and an RCT domain that recruits Sir proteins 3 and 4 (Sir3, Sir4) for gene silencing, and Rif1 and Rif2 for telomere length maintenance. Schizosaccharomyces pombe RAP1 (spRap1), like human RAP1, lacks direct DNA-binding activity and is localized to telomeres via Taz1, an ortholog of TRF1 and TRF2. The S. pompe RCT resembles the first 3-helix bundle of the yeast and human RCT forms, but is not included in this larger model. : Pssm-ID: 212167 Cd Length: 100 Bit Score: 87.77 E-value: 2.90e-21

BRCT domain, a BRCA1 C-terminus domain; This BRCT domain, a BRCA1 C-terminus region, is found on many RAP1 proteins, usually at the very N-terminus. The function in human at least of a BRCT is to contribute to the heterogeneity of the telomere DNA length, but that may not be its general function, which remains unknown. : Pssm-ID: 465186 [Multi-domain] Cd Length: 84 Bit Score: 67.78 E-value: 2.89e-14

DNA-binding modules of yeast Rap1 and related proteins; Yeast Rap1 DNA-binding activity is mediated by a pair of DNA-binding modules comprised of 2 3-helix bundles with an N-terminal arm, closely matching the structure of homeodomain and myb-type proteins. Human Rap1 has a single myb-like module, and may not bind DNA directly. Rap1, identified in budding yeast as repressor-activator protein 1, is a conserved telomere binding protein, also identified in fission yeast and mammals. In Saccharomyces cerevisiae, Rap1 directly binds DNA and is involved in transcriptional activation, gene silencing, as well as binding at numerous binding sites at each telomere, where it functions in telomere length regulation, telomeric position effect gene silencing and telomere end protection.

TRF2-interacting telomeric protein/Rap1 - C terminal domain; This family of proteins represents the C-terminal domain of the protein Rap-1, which plays a distinct role in silencing at the silent mating-type loci and telomeres. The Rap-1 C terminus adopts an all-helical fold. Rap1 carries out its function by recruiting the Sir3 and Sir4 proteins to chromatin via its C terminal domain. Rap1 is otherwise known as TRF2-interacting protein, as it is one of the six subunit components of the Shelterin complex. Shelterin protects telomere ends from attack by DNA-repair mechanisms. Model doesn't capture Sch. pombe as it cuts this sequence into two. Pssm-ID: 431966 Cd Length: 82 Bit Score: 58.80 E-value: 4.20e-11
