GO:0061821:   telomeric D-loop binding
Interacting selectively and non-covalently with a telomeric D-loop. A telomeric D-loop is a three-stranded DNA displacement loop that forms at the site where the telomeric 3" single-stranded DNA overhang (formed of the repeat sequence TTAGGG in mammals) is tucked back inside the double-stranded component of telomeric DNA molecule, thus forming a t-loop or telomeric-loop and protecting the chromosome terminus.
