CC -!- FUNCTION: Binds preferentially double-stranded telomeric repeats, but
CC may also bind to the single telomeric strand. {ECO:0000250}.
CC -!- SUBUNIT: Forms a homodimer and heterodimers. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000255|PROSITE-ProRule:PRU00625,
CC ECO:0000255|PROSITE-ProRule:PRU00837}. Chromosome {ECO:0000255|PROSITE-
CC ProRule:PRU00837}. Nucleus, nucleolus {ECO:0000250}. Chromosome,
CC telomere {ECO:0000305}. Note=Localized to the nucleolus during
CC interphase. {ECO:0000250}.
CC -!- DOMAIN: HTH myb-type domain confers double-stranded telomeric DNA-
CC binding while the H15 domain is involved in non-specific DNA-protein
CC interaction and multimerization. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the histone H1/H5 family. SMH subfamily.
CC {ECO:0000255|PROSITE-ProRule:PRU00837}.
