    What's a GeneRIF?
    1. 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.
      Title: Telomere binding protein TRB1 is associated with promoters of translation machinery genes in vivo.
    2. AtTRB1 is highly dynamic during interphase. The histone-like domain and the Myb domain can both direct the protein to the nucleolus.
      Title: AtTRB1, a telomeric DNA-binding protein from Arabidopsis, is concentrated in the nucleolus and shows highly dynamic association with chromatin.
    3. DNA-protein interaction of the full-length and truncated variants of AtTRB1, a Single-Myb-Histone-family member with a typical structure
      Title: Functional characterization of domains in AtTRB1, a putative telomere-binding protein in Arabidopsis thaliana.
    4. The domains responsible for that interaction AtTRB1 and AtPOT1b were identified.
