CC   -!- FUNCTION: Single-stranded telomeric DNA-binding protein that is
CC       required to protect the 3'-end telomeric overhang. It binds the
CC       consensus sequence 5'-GGTTAC-3'. Regulates telomerase and telomere
CC       length. {ECO:0000269|PubMed:11349150, ECO:0000269|PubMed:12463756,
CC       ECO:0000269|PubMed:18535244}.
CC   -!- SUBUNIT: Self-associates. Interacts with ccq1, poz1 and tpz1.
CC       {ECO:0000269|PubMed:12463756, ECO:0000269|PubMed:18535244}.
CC   -!- SUBCELLULAR LOCATION: Nucleus. Chromosome, telomere.
CC   -!- SIMILARITY: Belongs to the telombin family. {ECO:0000305}.
