Centromeric Alpha-Satellite DNA Adopts Dimeric i-Motif Structures Capped by AT Hoogsteen Base Pairs. Chemistry. 2015 Jun 26;21(27):9816-24.
Two C-rich strands of the Human centromeric alpha-satellite self-recognize forming an unusual DNA structure, suggesting that this non-canonical motif may play a role in the higher order nucleosome organization at the centromere
