Facts about RING1 and YY1-binding protein.
Component of a PRC1-like complex that mediates monoubiquitination of histone H2A'Lys-119' on the X chromosome and is needed for normal silencing of a single copy of the X chromosome in XX females. Inhibits ubiquitination and subsequent degradation of TP53, and thus plays a role in regulating transcription of TP53 target genes (PubMed:19098711).

Down-regulated in breast cancer tissues and in several breast cancer cell lines (at protein level) (PubMed:27748911). Widely expressed with highest levels in lymphoid tissues and placenta.
Nucleus. Cytoplasm. Nucleus, nucleoplasm. Primarily found in the nucleus. Detected in a punctate pattern likely to represent Polycomb group (PcG) bodies (By similarity).
PMID: 11395500 by Zheng L., et al. The death effector domain-associated factor plays distinct regulatory roles in the nucleus and cytoplasm.
PMID: 11953439 by Sawa C., et al. YEAF1/RYBP and YAF-2 are functionally distinct members of a cofactor family for the YY1 and E4TF1/hGABP transcription factors.
