    basic FUNCTION
  • involved in regulation of transcription
  • induced apoptosis in various tumor cell lines, but not in primary fibroblasts or mesenchymal cells
  • involved in the regulation of both cytoplasmic and nuclear events of apoptosis
  • inducing cell-cycle arrest and is involved in the TP53 response to DNA damage, interacting with MDM2 and decreasing MDM2-mediated TP53 ubiquitination, leading to stabilization of TP53 and an increase in TP53 activity (Chen 2009)
  • RYBP and IFT57 may functionally interact in the apoptotic processes that accompany normal murine neural development
  • zinc finger protein with an essential role during embryonic development, which binds transcriptional factors, Polycomb products, and mediators of apoptosis
  • CELLULAR PROCESS cell life, cell death/apoptosis
    nucleotide, transcription, regulation

    INTERACTION
    DNA binding
    RNA
    small molecule metal binding,
  • Zn2+
  • protein
  • binding to the Polycomb transcriptional repressor complex and to the transcription factor YY1
  • interacting specifically with the E2F2 and E2F3 family members (Schlisio 2002)
  • interacting with apoptin (Danen-van Oorschot 2004)
  • interacting with DED-containing proteins and encoding pro-apoptotic functions
  • RYBP can synergize with IFT57 to enhance CASP8-mediated apoptosis and also appears to be essential for IFT57-mediated apoptosis
  • interacting with MDM2 (Chen 2009)
  • RYBP stimulates the activity of RNF2 toward H2AK119ub1, suggesting a central role in Polycomb repressive complex 1 function
  • RYBP-Polycomb repressive complex 1 is recruited to target loci in embryonic stem cells and is also involved in XIST RNA-mediated silencing, the latter suggesting a wider role in Polycomb silencing
  • CBX7 is necessary for recruitment of RNF2 to chromatin, whereas RYBP enhances the Polycomb repressive complex 1 enzymatic activity
  • RYBP inhibits the polyubiquitination-mediated proteasomal degradation of RNF2 independently of its ubiquitin (Ub)-protein isopeptide ligase (E3) ligase activity
  • RYBP modulates stability and function of RNF2 through targeting UBE3A
