Chromatin regulator which modulates histone acetylation and gene expression in neural precursor cells (By similarity). May recruit histone deacetylases (HDACs) to the p160 coactivators/nuclear receptor complex to inhibit ligand-dependent transactivation (PubMed:15184363). Has a role in proliferation and development of cortical neural precursors (PubMed:25556659). May also regulate bone homeostasis (By similarity). Interacts with the PAS region of the p160 coactivators. Localizes to chromatin during prometaphase. Expression levels are regulated during the cell cycle, reaching maximal levels at M phase and then rapidly declining after late M phase. Subject to proteasomal degradation which is probably essential to regulate its activity. The disease is caused by variants affecting the gene represented in this entry. Contaminating sequence. Potential poly-A sequence.
