Gene : RBR1 A. thaliana

DB identifier  ? AT3G12280 Secondary Identifier  ? locus:2082194
Name  ? retinoblastoma-related 1 Brief Description  retinoblastoma-related 1
TAIR Computational Description  retinoblastoma-related 1;(source:Araport11)
TAIR Curator Summary  Encodes a retinoblastoma homologue RETINOBLASTOMA-RELATED protein (RBR or RBR1). RBR controls nuclear proliferation in the female gametophyte. Also required for correct differentiation of male gametophytic cell types. Regulates stem cell maintenance in Arabidopsis roots. Involved in the determination of cell cycle arrest in G1 phase after sucrose starvation. RBR1 is also involved in regulation of imprinted genes. Together with MSI1 it represses the expression of MET1. This in turn activates expression of the imprinted genes FIS2 and FWA. Functions as a positive regulator of the developmental switch from embryonic heterotrophic growth to autotrophic growth.ChIP studies indicate that one class of targets of RBR1 are transposable elements.
