General annotation (Comments)
| Function | Essential component of the NoRC (nucleolar remodeling complex) complex, a complex that mediates silencing of a fraction of rDNA by recruiting histone-modifying enzymes and DNA methyltransferases, leading to heterochromatin formation and transcriptional silencing. In the complex, it plays a central role by being recruited to rDNA and by targeting chromatin modifying enzymes such as HDAC1, leading to repress RNA polymerase I transcription. Recruited to rDNA via its interaction with TTF1 and its ability to recognize and bind histone H4 acetylated on 'Lys-16' (H4K16ac), leading to deacetylation of H4K5ac, H4K8ac, H4K12ac but not H4K16ac. Specifically binds pRNAs, 150-250 nucleotide RNAs that are complementary in sequence to the rDNA promoter; pRNA-binding is required for heterochromatin formation and rDNA silencing By similarity. |
| Subunit structure | Component of the NoRC complex, at least composed of SMARCA5/SNF2H and BAZ2A/TIP5. Interacts with TTF1; required for recruitment of the NoRC complex to rDNA. Interacts with DNMT1, DNM3B, HDAC1 and SIN3A By similarity. |
| Subcellular location | Nucleus › nucleolus By similarity. Note: Colocalizes with the basal RNA polymerase I transcription factor UBF in the nucleolus By similarity. |
| Tissue specificity | Expressed at moderate levels in most tissues analyzed, including heart, brain, placenta, lung, skeletal muscle, kidney and pancreas. |
| Domain | The bromo domain and the PHD-type zinc finger recognize and bind histone H4 acetylated on 'Lys-16' (H4K16ac). These 2 domains play a central role in the recritment of chromatin silencing proteins such as DNMT1, DNMT3B and HDAC1. The MBD (methyl-CpG-binding) domain, also named TAM domain, specifically recognizes and binds a conserved stem-loop structure the association within pRNA. Binding to pRNA induces a conformational change of BAZ2A/TIP5 and is essential for targeting the NoRC complex to the nucleolus By similarity. |
| Post-translational modification | Acetylation at Lys-680 by KAT8/MOF promotes its dissociation from pRNA, affecting heterochromatin formation, nucleosome positioning and rDNA silencing. Deacetylation by SIRT1 in late S phase enhances pRNA-binding, allowing de novo DNA methylation and heterochromatin formation. Acetylation is high during S phase and declines to background levels in late S phase when the silent copies of rRNA genes are replicated By similarity. |
| Sequence similarities | Belongs to the WAL family. Contains 4 A.T hook DNA-binding domains. Contains 1 bromo domain. Contains 1 DDT domain. Contains 1 MBD (methyl-CpG-binding) domain. Contains 1 PHD-type zinc finger. |
| Sequence caution | The sequence AAB60864.1 differs from that shown. Reason: Contaminating sequence. Potential poly-A sequence. The sequence BAG51228.1 differs from that shown. Reason: Erroneous termination at position 168. Translated as Tyr. |
