Function

Transcriptional coregulator which can act as both a transcriptional corepressor and coactivator. As a part of the histone-deacetylase multiprotein complex (NuRD), regulates transcription of its targets by modifying the acetylation status of the target chromatin and cofactor accessibility to the target DNA. In conjunction with other components of NuRD, acts as a transcriptional corepressor of BRCA1, ESR1, TFF1 and CDKN1A. Acts as a transcriptional coactivator of BCAS3, PAX5 and SUMO2, independent of the NuRD complex. Stimulates the expression of WNT1 by inhibiting the expression of its transcriptional corepressor SIX3. Plays a role in the inflammatory responses, both as a target and as a component of the NF-kappa-B signaling and regulates a subset of proinflammatory cytokines such as IL1B, MIP2, and TNF. Regulates p53-dependent and -independent DNA repair processes following genotoxic stress. Regulates the stability and function of p53/TP53 by inhibiting its ubiquitination by COP1 and MDM2 thereby regulating the p53-dependent DNA repair. Plays an important role in tumorigenesis, tumor invasion, and metastasis. Plays a role in the regulation of the circadian clock and is essential for the generation and maintenance of circadian rhythms under constant light and for normal entrainment of behavior to light-dark (LD) cycles. Positively regulates the CLOCK-ARNTL/BMAL1 heterodimer mediated transcriptional activation of its own transcription and the transcription of CRY1. Regulates deacetylation of ARNTL/BMAL1 by regulating SIRT1 expression, resulting in derepressing CRY1-mediated transcription repression. {ECO:0000269PubMed:17671180, ECO:0000269PubMed:19805145, ECO:0000269PubMed:19837670, ECO:0000269PubMed:20071335, ECO:0000269PubMed:20519513, ECO:0000269PubMed:20682799, ECO:0000269PubMed:21965678, ECO:0000269PubMed:24089055}.

Subcellular Localization

Nucleus. Nucleus envelope {ECO:0000255PROSITE-ProRule:PRU00512, ECO:0000255PROSITE- ProRule:PRU00624}. Cytoplasm. Cytoplasm, cytoskeleton {ECO:0000250}. Note=Associated with microtubules. Primarily localized in the cytoplasm in embryonic tissues. Localization at the nuclear envelope is TPR-dependent.
