== Function ==
[https://www.uniprot.org/uniprot/ACD_HUMAN ACD_HUMAN] Component of the shelterin complex (telosome) that is involved in the regulation of telomere length and protection. Shelterin associates with arrays of double-stranded TTAGGG repeats added by telomerase and protects chromosome ends; without its protective activity, telomeres are no longer hidden from the DNA damage surveillance and chromosome ends are inappropriately processed by DNA repair pathways. Promotes binding of POT1 to single-stranded telomeric DNA. Modulates the inhibitory effects of POT1 on telomere elongation. The ACD-POT1 heterodimer enhances telomere elongation by increasing telomerase processivity. Plays a role in shelterin complex assembly. May play a role in organogenesis.<ref>PMID:15181449</ref> <ref>PMID:16166375</ref> <ref>PMID:16880378</ref> <ref>PMID:20231318</ref> <ref>PMID:17237768</ref>
