  • Function
    Constitutes one of the E3 ubiquitin-protein ligases that mediate monoubiquitination of 'Lys-119' of histone H2A, thereby playing a central role in histone code and gene regulation. H2A 'Lys-119' ubiquitination gives a specific tag for epigenetic transcriptional repression and participates in X chromosome inactivation of female mammals. Essential component of the Polycomb group (PcG) multiprotein PRC1 complex, a complex required to maintain the transcriptionally repressive state of many genes, including Hox genes, throughout development. PcG PRC1 complex act via chromatin remodeling and modification of histones, rendering chromatin heritably changed in its expressibility. Compared to RNF2/RING2, it does not have the main E3 ubiquitin ligase activity on histone H2A, and it may rather act as a modulator of RNF2/RING2 activity.

  • Lane 1: Wild-type HAP1 cell lysate (40 µg)
    Lane 2: RING1 knockout HAP1 cell lysate (40 µg)
    Lane 3: MOLT4 cell lysate (20 µg)
    Lane 4: LnCaP cell lysate (20 µg)
    Lanes 1 - 4: Merged signal (red and green). Green - ab175149 observed at 50 kDa. Red - loading control, ab181602, observed at 37 kDa.

    ab175149 was shown to specifically react with RING1 when RING1 knockout samples were used. Wild-type and RING1 knockout samples were subjected to SDS-PAGE. Ab175149 and ab181602 (loading control to GAPDH) were diluted at 1/500 and 1/10000 dilution respectively and incubated overnight at 4C. Blots were developed with Goat anti-Mouse IgG H&L (IRDye® 800CW) preadsorbed ab216772 and Goat Anti-Rabbit IgG H&L (IRDye® 680RD) preadsorbed ab216777 secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
