Telomere length regulation protein conserved(IPR019337) is a conserved domain telomere length regulation protein. The group of proteins known as telomere length regulation TEL2 or clock aberrant protein-2 contains a conserved domain. Plants and humans share these proteins. These proteins contribute to the silencing of subtelomeric regions and modulate telomere length. Tel2 participates in the initial phase of the TEL1/ATM pathway of DNA damage signaling. The protein binds to telomeric DNA repeat sequences in vitro.
