Adrenocortical dysplasia protein homolog (ACD)

Part of the shelterin complex (telosome) which 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.

With no protective action, telomeres are no longer hidden from the DNA damage surveillance and chromosome ends are inappropriately processed by DNA repair pathways. Promotes binding of POT1 into single-stranded telomeric DNA.
