Supplementary information

KAT7 also known as Hbo1 KAT-7 MYST2 KAT-7 and Katset functions as a histone acetyltransferase specifically modifying histone H4 at lysine 12 5 and 8. With a molecular mass typically around 63 kDa KAT7 is expressed in nucleus and localizes to chromatin. It associates with chromatin during DNA replication and is vital in histone H4 acetylation facilitating chromatin remodeling and gene expression.
Biological function summary

This protein plays a significant role in transcription regulation and DNA replication. KAT7 is a component of the HBO1 complex working together with other proteins like JADE1/2/3 BRPF1/2/3 and ING4/5 making it integral to cell cycle progression and transcriptional activation. This complex is essential for initiating DNA replication as it acetylates histones and regulates chromatin accessibility necessary for DNA synthesis.

Pathways

KAT7/Hbo1/MYST2 is actively engaged in the transcriptional regulatory network and DNA replication pathways. It influences gene expression through its interaction with the transcriptional machinery and by modifying the chromatin structure. Within these pathways it interacts with proteins like BRPF1 and ING5 enhancing transcription and replication. This positions KAT7 as an important component in ensuring cellular growth and division through its histone acetylation activities.

Research indicates a link between KAT7 function and cancer. Its dysregulation contributes to tumorigenesis related to its role in cell proliferation and gene expression. KAT7 affects the expression of oncogenes and interacts with proteins like p53. Altered KAT7 activity disrupts normal cellular processes and in cancer results in aberrant cell cycle regulation and uncontrolled cell proliferation highlighting its potential as a therapeutic target in oncology.

Target data

Catalytic subunit of histone acetyltransferase HBO1 complexes, which specifically mediate acetylation of histone H3 at 'Lys-14' (H3K14ac), thereby regulating various processes, such as gene transcription, protein ubiquitination, immune regulation, stem cell pluripotent and self-renewal maintenance and embryonic development (PubMed : 16387653, PubMed : 21753189, PubMed : 24065767, PubMed : 26620551, PubMed : 31767635, PubMed : 31827282). Some complexes also catalyze acetylation of histone H4 at 'Lys-5', 'Lys-8' and 'Lys-12' (H4K5ac, H4K8ac and H4K12ac, respectively), regulating DNA replication initiation, regulating DNA replication initiation (PubMed : 10438470, PubMed : 19187766, PubMed : 20129055, PubMed : 24065767). Specificity of the HBO1 complexes is determined by the scaffold subunit : complexes containing BRPF scaffold (BRPF1, BRD1/BRPF2 or BRPF3) direct KAT7/HBO1 specificity towards H3K14ac, while complexes containing JADE (JADE1, JADE2 and JADE3) scaffold direct KAT7/HBO1 specificity towards histone H4 (PubMed : 19187766, PubMed : 20129055, PubMed : 24065767, PubMed : 26620551). H3K14ac promotes transcriptional elongation by facilitating the processivity of RNA polymerase II (PubMed : 31827282). Acts as a key regulator of hematopoiesis by forming a complex with BRD1/BRPF2, directing KAT7/HBO1 specificity towards H3K14ac and promoting erythroid differentiation (PubMed : 21753189). H3K14ac is also required for T-cell development (By similarity). KAT7/HBO1-mediated acetylation facilitates two consecutive steps, licensing and activation, in DNA replication initiation : H3K14ac facilitates the activation of replication origins, and histone H4 acetylation (H4K5ac, H4K8ac and H4K12ac) facilitates chromatin loading of MCM complexes, promoting DNA replication licensing (PubMed : 10438470, PubMed : 11278932, PubMed : 18832067, PubMed : 19187766, PubMed : 20129055, PubMed : 21856198, PubMed : 24065767, PubMed : 26620551). Acts as a positive regulator of centromeric CENPA assembly : recruited to centromeres and mediates histone acetylation, thereby preventing centromere inactivation mediated by SUV39H1, possibly by increasing histone turnover/exchange (PubMed : 27270040). Involved in nucleotide excision repair : phosphorylation by ATR in response to ultraviolet irradiation promotes its localization to DNA damage sites, where it mediates histone acetylation to facilitate recruitment of XPC at the damaged DNA sites (PubMed : 28719581). Acts as an inhibitor of NF-kappa-B independently of its histone acetyltransferase activity (PubMed : 16997280).. Plays a central role in the maintenance of leukemia stem cells in acute myeloid leukemia (AML) (PubMed : 31827282). Acts by mediating acetylation of histone H3 at 'Lys-14' (H3K14ac), thereby facilitating the processivity of RNA polymerase II to maintain the high expression of key genes, such as HOXA9 and HOXA10 that help to sustain the functional properties of leukemia stem cells (PubMed : 31827282).
