Oberon_cc is the coiled-coil region of Oberon proteins from plants. Oberon is necessary for maintenance and/or establishment of both the shoot and root apical meristems in Arabidopsis. Most Oberon proteins carry a PHD finger domain, Pfam:PF07227 and this coiled-coil domain [1]. Oberon proteins mediate the TMO7 (the direct target of MP) expression through modification of, or binding to, chromatin at the TMO7 locus. TMO7 stands for the target of Monopteros 7 (or Auxin response factor 7) [2].
