Protein Structure
UniProt Annotation
Function Histone acetyltransferase which may be involved in both positive and negative regulation of transcription. Required for RUNX2-dependent transcriptional activation. May be involved in cerebral cortex development. Component of the MOZ/MORF complex which has a histone H3 acetyltransferase activity. {ECO:0000269PubMed:10497217, ECO:0000269PubMed:11965546, ECO:0000269PubMed:16387653}.
Subcellular Localization Nucleus {ECO:0000305}.
Disease Associations Note=A chromosomal aberration involving KAT6B may be a cause acute myeloid leukemias. Translocation t(10;16)(q22;p13) with CREBBP.Ohdo syndrome, SBBYS variant (SBBYSS) [MIM:603736]: A syndrome characterized by distinctive facial appearance with severe blepharophimosis, an immobile mask-like face, a bulbous nasal tip, and a small mouth with a thin upper lip. The condition presents in infancy with severe hypotonia and feeding problems. Associated skeletal problems include joint laxity, abnormally long thumbs and great toes, and dislocated or hypoplastic patellae. Structural cardiac defects are present in around 50% of cases, and dental anomalies, including small and pointed teeth, are common. Optic atrophy and conductive or sensorineural deafness are repeatedly reported. Many affected individuals have abnormalities of thyroid structure or function. SBBYSS is usually associated with severe mental retardation, delayed motor milestones, and significantly impaired speech. {ECO:0000269PubMed:22077973}. Note=The disease is caused by mutations affecting the gene represented in this entry.Genitopatellar syndrome (GTPTS) [MIM:606170]: A rare disorder consisting of microcephaly, severe psychomotor retardation, and characteristic coarse facial features, including broad nose and small or retracted chin, associated with congenital flexion contractures of the lower extremities, abnormal or missing patellae, and urogenital anomalies. {ECO:0000269PubMed:22265014}. Note=The disease is caused by mutations affecting the gene represented in this entry.
Tissue Specificity Ubiquitously expressed, with high levels in heart, pancreas, testis and ovary. {ECO:0000269PubMed:10497217}.
