Functional Description ? help Back to Top
Source Description
TAIREncodes a telomeric DNA binding protein. In vitro, an N-terminal Myb domain enables it to interact with double-stranded telomeric repeats.
UniProtBinds preferentially double-stranded telomeric repeats. {ECO:0000269|PubMed:19102728}.
Function -- GeneRIF ? help Back to Top
  1. The domains responsible for that interaction AtTRB1 and AtPOT1b were identified.
    [PMID: 18387366]
  2. DNA-protein interaction of the full-length and truncated variants of AtTRB1, a Single-Myb-Histone-family member with a typical structure
    [PMID: 18479720]
  3. AtTRB1 is highly dynamic during interphase. The histone-like domain and the Myb domain can both direct the protein to the nucleolus.
    [PMID: 19947985]
  4. TRB1 shows a specific genome-wide distribution pattern which suggests its role in regulation of genes involved in biogenesis of the translational machinery, in addition to its preferential telomeric localization.
