Overview

Zinc finger MYND-type containing 8 (ZMYND8) is a human chromatin-associated protein characterized by a MYND-type zinc finger, a bromodomain, and a plant homeodomain (PHD) finger. It acts as an epigenetic "reader," recognizing specific acetylated lysine residues on histone tails—particularly H3K14ac and H4K16ac—thereby regulating transcription, genome stability, and DNA double-strand break repair. ZMYND8 interacts with DNA repair machinery at damaged chromatin and collaborates with other zinc finger proteins and PARP1 to promote homologous recombination. Reduced or epigenetically silenced expression of ZMYND8 has been linked to a worse prognosis and increased genomic instability in cancers, positioning it as a potential tumor suppressor and biomarker in oncology[1][6][8][10].

Mechanism of action

Chromatin reader-binding to acetylated histone lysine residues, regulating gene expression and DNA damage response; Protein–protein interaction via MYND domain, recruiting other DNA repair or chromatin-associated factors

03

Biological functions

Regulation of DNA-templated transcriptionGenome stability maintenanceDNA damage repairChromatin remodelingCell proliferation and differentiation
04

Disease associations

Cancer (notably colorectal and other solid tumors)Genome instability-related disorders
05

Safety considerations

No direct safety concerns currently established for ZMYND8-targeted interventions; off-target effects common to chromatin modifier targeting may be relevant
06

Interacting drugs

No specific drugs directly targeting ZMYND8 are currently approved; however, its bromodomain reader function suggests potential for epigenetic drug targeting
07

Biomarkers

ZMYND8 expression as a prognostic marker in colorectal cancer and potentially other cancers
