Function

Histone acetyltransferase that catalyzes histone H4 acetylation at 'Lys-5'- and 'Lys-8' (H4K5ac and H4K8ac) or 'Lys-16' (H4K16ac), depending on the context (PubMed:12397079, PubMed:16227571, PubMed:16543150, PubMed:20018852, PubMed:21217699, PubMed:22020126, PubMed:22547026, PubMed:31794431, PubMed:33837287). Catalytic component of the MSL histone acetyltransferase complex, a multiprotein complex that mediates the majority of histone H4 acetylation at 'Lys-16' (H4K16ac), an epigenetic mark that prevents chromatin compaction (PubMed:12397079, PubMed:16227571, PubMed:16543150, PubMed:21217699, PubMed:22020126, PubMed:22547026, PubMed:33657400, PubMed:33837287). H4K16ac constitutes the only acetylation mark intergenerationally transmitted and regulates key biological processes, such as oogenesis, embryonic stem cell pluripotency, hematopoiesis or glucose metabolism (By similarity). The MSL complex is required for chromosome stability and genome integrity by maintaining homeostatic levels of H4K16ac (PubMed:33837287). The MSL complex is also involved in gene dosage by promoting up-regulation of genes expressed by the X chromosome (By similarity). X up-regulation is required to compensate for autosomal biallelic expression (By similarity). The MSL complex also participates in gene dosage compensation by promoting expression of Tsix non-coding RNA (By similarity). As part of the NSL histone acetyltransferase complex, catalyzes histone H4 acetylation at 'Lys-5'- and 'Lys-8' (H4K5ac and H4K8ac) at transcription start sites and promotes transcription initiation (PubMed:20018852, PubMed:22547026, PubMed:33657400). The NSL complex also acts as a regulator of gene expression in mitochondria: KAT8 associates with mitochondrial DNA and controls expression of respiratory genes in an acetyltransferase-dependent mechanism (PubMed:27768893). Also functions as an acetyltransferase for non-histone targets, such as ALKBH5, COX17, IRF3, KDM1A/LSD1, LMNA, PAX7 or TP53/p53 (PubMed:17189187, PubMed:19854137, PubMed:37369679). Acts as an inhibitor of antiviral immunity by acetylating IRF3, preventing IRF3 recruitment to promoters (By similarity). Acts as a regulator of asymmetric division in muscle stem cells by mediating acetylation of PAX7 (By similarity). As part of the NSL complex, acetylates TP53/p53 at 'Lys-120' (PubMed:17189187, PubMed:19854137). Acts as a regulator of epithelial-to-mesenchymal transition as part of the NSL complex by mediating acetylation of KDM1A/LSD1 (PubMed:27292636). The NSL complex is required for nuclear architecture maintenance by mediating acetylation of LMNA (By similarity). Promotes mitochondrial integrity by catalyzing acetylation of COX17 (By similarity). In addition to protein acetyltransferase activity, able to mediate protein propionylation (PubMed:29321206).

Activity summary

The KAT8 protein also known as MYST1 or MOF functions as a histone acetyltransferase. It acetylates histone H4 at lysine 16 which is critical for chromatin structure and gene expression regulation. The molecular mass of KAT8 is approximately 55 kDa. This protein shows high expression in testis and is also present in other tissues. KAT8 is part of the MYST family of acetyltransferases sharing similarities with other MYST family proteins such as MOF protein.

Biological function summary

KAT8 plays an essential role in gene transcription regulation by forming part of a complex known as the MSL (Male-Specific Lethal) complex. This complex ensures dosage compensation in Drosophila by adjusting gene expression levels. KAT8 is vital for the maintenance of chromatin structure influencing gene activation and silencing across various biological systems. It interacts with several co-factors during transcription regulation further highlighting its functional significance in the epigenetic landscape.

Pathways

KAT8 engages in processes linked to chromatin modification and gene expression. Specifically it plays a significant role in the pathways of chromatin organization and transcriptional regulation by RNA polymerase II. The protein ENL participates in related pathways and interacts with KAT8 during transcription elongation. These interactions highlight KAT8's role in epigenetic regulation affecting multiple genes' transcription states.

Associated diseases and disorders

KAT8 is associated with cancers and neurodevelopmental disorders. Aberrant expression or mutations in KAT8 have been observed in certain cancers making it a potential target for therapeutic intervention. In neurodevelopmental disorders changes in KAT8 acetyltransferase activity affect neuronal gene expression implicating it in disorders linked to cognitive deficits. Another protein TIP60 shows functional overlap with KAT8 in these conditions suggesting interconnected roles in disease pathogenesis.
