Functional characterization of domains in AtTRB1, a putative telomere-binding protein in Arabidopsis thaliana

AtTRB1 is a telomeric-dsDNA-binding protein which is able to form multimers. The specific binding to telomeric DNA is primarily conducted by the Myb domain, while the multimerization and sequence-non-specific interactions with DNA are mediated by the H1/5 domain.
