Chromatin regulator which modulates histone acetylation and gene expression in neural precursor cells (PubMed:25556659). May recruit histone deacetylases (HDACs) to the p160 coactivators/nuclear receptor complex to inhibit ligand-dependent transactivation (By similarity). Has a role in proliferation and development of cortical neural precursors (PubMed:25556659). May also regulate bone homeostasis (PubMed:17986521). Interacts with the PAS region of the p160 coactivators. Localizes to chromatin during prometaphase (By similarity). Detected in the cerebral cortex from embryonic stage 11 dpc through to postnatal stage P3, where it is primarily expressed in neural precursors. Subject to proteasomal degradation which is probably essential to regulate its activity.
