KAT7
KAT7 (Histone acetyltransferase KAT7) is a gene whose normal job is to hold cell growth in check. The public catalogues list it as a tumour suppressor and a DNA repair gene, and it is called a cancer driver by mutation analysis of patient cohorts. Tied to Bladder & urothelial cancer.
Overview
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. Some complexes also catalyse 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. 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.
IntOGen calls it a driver in 1 cohort (0 activating, 1 loss-of-function), covering Bladder Urothelial Carcinoma.

- 2 · What goes wrong in cancer
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.
- 3 · How drugs use it
No product in this corpus aims at KAT7 yet. Because the protein is lost rather than overactive, drugs either restore its function or exploit the weakness its loss leaves (synthetic lethality).

Biology

H3K14ac promotes transcriptional elongation by facilitating the processivity of RNA polymerase II. Acts as a key regulator of haematopoiesis by forming a complex with BRD1/BRPF2, directing KAT7/HBO1 specificity towards H3K14ac and promoting erythroid differentiation. H3K14ac is also required for T-cell development. Location: Nucleus; Chromosome; Chromosome, centromere; Cytoplasm, cytosol (UniProt). Locus 17q21.33 (HGNC).

Notes
top- Written by scripts/fetch-cancer-genes.ts from CIViC, Open Targets, IntOGen, HGNC and UniProt; the function text is UniProt's, condensed and in UK spelling. Roles: IntOGen calls it a loss-of-function (LoF) driver in 1 cohort; UniProt keyword "DNA repair". Evidence tier "cohort-driver" is the strongest of those signals.
- Prevalence not recorded: none of the sources gives a positivity rate.
