Domain relationships



This entry represents a plant homeodomain (PHD) finger domain of Oberon proteins from plants. Oberon is necessary for maintenance and/or establishment of both the shoot and root apical meristems in Arabidopsis. Oberon proteins are made up of a PHD finger domain and a coiled-coil domain. The PHD-finger domain is found in a wide variety of proteins involved in the regulation of chromatin structure [PMID: 18403411]. 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 (MP) (or Auxin response factor 7) [PMID: 22378640].

This domain can also be found in protein VERNALIZATION INSENSITIVE 3 (VIN3) and related proteins. VIN3 is involved in both the vernalization and photoperiod pathways in Arabidopsis [PMID: 17114575]. VIN3-like protein 1 (also known as VRN5) functions in the epigenetic silencing of Arabidopsis FLOWERING LOCUS C [PMID: 17174094].
