| Sequence status | Complete. |
| Protein existence | Evidence at transcript level |
General annotation (Comments)
| Function | Histone acetyltransferase which may be involved in both positive and negative regulation of transcription. Required for RUNX2-dependent transcriptional activation. Component of the MOZ/MORF complex which has a histone H3 acetyltransferase activity By similarity. Involved in cerebral cortex development. Ref.1 |
| Catalytic activity | Acetyl-CoA + [histone] = CoA + acetyl-[histone]. Ref.1 |
| Subunit structure | Component of the MOZ/MORF complex composed at least of ING5, KAT6A, KAT6B, MEAF6 and one of BRPF1, BRD1/BRPF2 and BRPF3 By similarity. Interacts with RUNX1 and RUNX2 By similarity. |
| Subcellular location | Nucleus Probable. |
| Tissue specificity | Ubiquitously expressed. Ref.1 |
| Developmental stage | Strongly expressed in the ventricular zone of the developing cerebral cortex. Ref.1 |
| Domain | The N-terminus is involved in transcriptional activation while the C-terminus is involved in transcriptional repression By similarity. |
| Post-translational modification | Autoacetylated By similarity. Autoacetylation at Lys-633 is required for proper function By similarity. |
| Disruption phenotype | Mice have a low body weight, craniofacial abnormalities, and defects in cortex development. Mice carrying a gene trap insertion in the gene, produces approximately 5% of the normal amount of mRNA. The hypomorphic mutant displays a number of defects that mirror SBBYSS syndrome, although the phenotype is milder. Mice are of normal size at birth but fail to thrive and have brain developmental defects as well as craniofacial defects. Observed abnormalities include short and narrow palpebral fissures, low set ears, and malocclusion. Similar to individuals with SBBYSS, mice carrying the gene trap insertion have long, slender feet and disproportionally long first digits. Ref.1 Ref.5 |
| Sequence similarities | Belongs to the MYST (SAS/MOZ) family. Contains 1 C2HC-type zinc finger. Contains 1 H15 (linker histone H1/H5 globular) domain. Contains 2 PHD-type zinc fingers. |
