X30_DNA (DF0001282)

Conserved repeat present in placental mammals and marsupials.


Basically a long hairpin with a loop from pos 158-230. The terminal bases may be TSDs. Present at orthologous sites in placentals and marsupials, absent from platypus.


  1. Distinct groups of repetitive families preserved in mammals correspond to different periods of regulatory innovations in vertebrates.
