CC   -!- FUNCTION: Component of the shelterin complex (telosome) that is
CC       involved in the regulation of telomere length and protection. Shelterin
CC       associates with arrays of double-stranded TTAGGG repeats added by
CC       telomerase and protects chromosome ends; without its protective
CC       activity, telomeres are no longer hidden from the DNA damage
CC       surveillance and chromosome ends are inappropriately processed by DNA
CC       repair pathways. Plays a role in shelterin complex assembly (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Monomer. Found in a complex with POT1; TERF1 and TNKS1.
CC       Component of the shelterin complex (telosome) composed of TERF1, TERF2,
CC       TINF2, TERF2IP, ACD and POT1 (By similarity). Interacts with TERF1.
CC       {ECO:0000250, ECO:0000269|PubMed:19487455}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}. Chromosome, telomere
CC       {ECO:0000250}.
CC   -!- DOMAIN: The TBM domain mediates interaction with TERF1. {ECO:0000250}.
