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.
细胞定位
Nucleus . Cytoplasm . Nucleus, nucleoplasm . Primarily found in the nucleus. Detected in a punctate pattern likely to represent Polycomb group (PcG) bodies (By similarity). .
功能
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 . 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 . May also regulate the ubiquitin-mediated proteasomal degradation of other proteins like FANK1 to regulate apoptosis . May be implicated in the regulation of the transcription as a repressor of the transcriptional activity of E4TF1 . May bind to DNA (By similarity). May play a role in the repression of tumor growth and metastasis in breast cancer by down-regulating SRRM3 .
