Telomere zinc finger-associated protein (ZBTB48)

Telomere-binding protein that functions as a regulator of telomere length (PubMed:28500257, PubMed:28082411). Directly binds the telomeric double-stranded 5'-TTAGGG-3' replicate (PubMed:28500257, PubMed:28082411).

Preferentially binds to telomeres that have a low concentration of shelterin complex and acts as a regulator of telomere length by initiating telomere trimming, a process that prevents the accumulation of aberrantly long telomeres (PubMed:28082411). Also functions as a transcription regulator that binds to promoter regions (PubMed:7969177, PubMed:24382891, PubMed:28500257).
