CC -!- FUNCTION: Constitutes one of the E3 ubiquitin-protein ligases that
CC mediate monoubiquitination of 'Lys-119' of histone H2A, thereby playing
CC a central role in histone code and gene regulation. H2A 'Lys-119'
CC ubiquitination gives a specific tag for epigenetic transcriptional
CC repression and participates in X chromosome inactivation of female
CC mammals. Essential component of a Polycomb group (PcG) multiprotein
CC PRC1-like complex, a complex class required to maintain the
CC transcriptionally repressive state of many genes, including Hox genes,
CC throughout development. PcG PRC1 complex acts via chromatin remodeling
CC and modification of histones, rendering chromatin heritably changed in
CC its expressibility. Compared to RNF2/RING2, it does not have the main
CC E3 ubiquitin ligase activity on histone H2A, and it may rather act as a
CC modulator of RNF2/RING2 activity (By similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=S-ubiquitinyl-[E2 ubiquitin-conjugating enzyme]-L-cysteine +
CC [acceptor protein]-L-lysine = [E2 ubiquitin-conjugating enzyme]-L-
CC cysteine + N(6)-ubiquitinyl-[acceptor protein]-L-lysine.;
CC EC=2.3.2.27;
CC -!- PATHWAY: Protein modification; protein ubiquitination.
CC -!- SUBUNIT: Component of chromatin-associated Polycomb (PcG) complexes.
CC Part of the E2F6.com-1 complex in G0 phase composed of E2F6, MGA, MAX,
CC TFDP1, CBX3, BAT8, EUHMTASE1, RING1, RNF2/RING2 MBLR, L3MBTL2 and YAF2.
CC Interacts with CBX2 and PCGF6. Component of a PRC1-like complex.
CC Component of repressive BCOR complex containing Polycomb group
CC subcomplex at least composed of RYBP, PCGF1, BCOR and RNF2/RING2.
CC Interacts with BMI1, PHC2, PCGF2, RNF2; CBX6, CBX7 and CBX8 (By
CC similarity). Interacts with MN1 (By similarity). {ECO:0000250,
CC ECO:0000250|UniProtKB:Q06587}.
CC -!- SUBCELLULAR LOCATION: Nucleus speckle {ECO:0000250}.
