Function
Component of a Polycomb group (PcG) multiprotein PRC1-like complex, a complex class required to maintain the transcriptionally repressive state of many genes, including Hox genes, throughout development. PcG PRC1-like complex acts via chromatin remodeling and modification of histones; it mediates monoubiquitination of histone H2A 'Lys-119', rendering chromatin heritably changed in its expressibility (PubMed:25519132). Component of a PRC1-like complex that mediates monoubiquitination of histone H2A 'Lys-119' on the X chromosome and is required for normal silencing of one copy of the X chromosome in XX females. May stimulate ubiquitination of histone H2A 'Lys-119' by recruiting the complex to target sites (By similarity). Inhibits ubiquitination and subsequent degradation of TP53, and thereby plays a role in regulating transcription of TP53 target genes (PubMed:19098711). May also regulate the ubiquitin-mediated proteasomal degradation of other proteins like FANK1 to regulate apoptosis (PubMed:14765135, PubMed:27060496). May be implicated in the regulation of the transcription as a repressor of the transcriptional activity of E4TF1 (PubMed:11953439). May bind to DNA. UniProt

Subunit Structure
Monomer. Component of repressive BCOR complex containing Polycomb group subcomplex at least composed of BCOR, PCGF1, RING1 and RNF2/RING2 (PubMed:16943429). Component of PCR1-like complexes (PubMed:26687479, PubMed:20696397). Interacts with PCGF1 (PubMed:26687479). Part of a PCR1-like complex that contains AUTS2, PCGF5, RNF2, CSNK2B AND RYBP (PubMed:25519132). Interacts with RNF2; the interaction is direct (PubMed:20696397). Interacts with CBX2, YAF2, RING1 and RNF2 (By similarity). Interacts with ubiquitin and ubiquitinated proteins (By similarity). Interacts with ubiquitinated histone H2A (By similarity). Interacts with apoptin, DEDD, FADD, CASP8, CASP10, YY1 and GABPB1 (PubMed:11395500, PubMed:11953439, PubMed:14765135). Together with GABPB1 and YY1, it forms a ternary complex, probably being the bridge factor between these two transcription factors (PubMed:11953439). Interacts with MDM2, and thereby inhibits ubiquitination of TP53 (PubMed:19098711). Identified in a ternary complex containing MDM2, TP53 and RYBP (PubMed:19098711). Interacts with FANK1; may prevent the ubiquitin-mediated proteasomal degradation of FANK1 (PubMed:27060496). Interacts with IFT57. UniProt

Data origin/color codes
The vertical color bar on the left side indicates data provenance.
Data in green originates from UniProtKB  
Variation data (sourced from UniProt) shows non-genetic variation from the ExPASy   and dbSNP   websites.
Data in yellow originates from Pfam  , by interacting with the HMMER3 web site  
Data in purple originates from Phosphosite  .
Data in orange originates from the SCOP   (version 1.75) and SCOPe   (version 2.04) classifications.
Data in grey has been calculated using BioJava  . Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  
  • Red: potentially disorderd region
  • Blue: probably ordered region.
Hydropathy has been calculated using a sliding window of 15 residues and summing up scores from standard hydrophobicity tables.
  • Red: hydrophobic
  • Blue: hydrophilic.
Data in lilac represent the genomic exon structure projected onto the UniProt sequence.
Data in blue originates from PDB
  • Secstruc: Secondary structure projected from representative PDB entries onto the UniProt sequence.
Sequence Mismatches It is now possible to see information about expression tags, cloning artifacts, and many other details related to sequence mismatches.
Icons represent a number of different sequence modifications that can be observed in PDB files. For example the 'T' icon T represents expression tags that have been added to the sequence. The 'E' icon E represents an engineered mutation. However, besides these two, there are many other icons. For more information about the meaning and exact position of a sequence modification, move the cursor over the icon.
