Target Background

Function
E3 ubiquitin-protein ligase that limits organ size, and possibly seed size, in a dose-dependent manner. Negatively regulates the duration of cell proliferation in leaves and petals independently of the major phytohormones (e.g. auxin, cytokinin, gibberellin, brassinosteroids, ethylene, abscisic acid, jasmonic acid), probably by targeting growth stimulators for degradation. Limits the proliferation of root meristematic cells. Polyubiquitinates DA1. Involved in the promotion of leaf senescence, in addition to its function in restricting plant growth. Possesses E3 ubiquitin-protein ligase activity in vitro.
Gene References into Functions
  1. BB acts conceptually similarly in leaf(-like) organs and the primary root, and uncouples cell proliferation from elongation in the root meristem. PMID: 28922745
  2. Big brother protein role in controlling leaf growth and senescence PMID: 28003326
  3. Genetic analyses show that DA2 functions synergistically with DA1 to regulate seed size, but does so independently of EOD1. Further results reveal that DA2 interacts physically with DA1 in vitro and in vivo. PMID: 24045020
  4. Conserved cis-elements are important for regulation of BB expression. PMID: 22433627
  5. The E3 ubiquitin ligase BIG BROTHER controls arabidopsis organ size in a dosage-dependent manner. PMID: 16461280
