Protein

RING1 and YY1-binding protein

Gene

RYBP

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Inhibits ubiquitination and subsequent degradation of TP53, and thereby plays a role in regulating transcription of TP53 target genes. May be implicated in the regulation of the transcription as a repressor of the transcriptional activity of E4TF1. May bind to DNA. Promotes apoptosis.4 Publications

Interactioni

Subunit structurei

Monomer. Interacts with apoptin, DEDD, FADD, CASP8, CASP10, YY1 and GABPB1. Component of repressive BCOR complex containing Polycomb group subcomplex at least composed of BCOR, PCGF1, RING1 and RNF2/RING2. Together with GABPB1 and YY1, it forms a ternary complex, probably being the bridge factor between these two transcription factors. Interacts with CBX2, YAF2, RING1 and RNF2. Interacts with ubiquitin and ubiquitinated proteins. Interacts with ubiquitinated histone H2A (By similarity). Interacts with MDM2, and thereby inhibits ubiquitination of TP53. Identified in a ternary complex containing MDM2, TP53 and RYBP. Interacts with PCGF1 (PubMed:26687479).By similarity7 Publications

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
