Overview

Zinc finger MIZ-type containing protein 1 (ZMIZ1) is a transcriptional coactivator and chromatin remodeler within the PIAS family, possessing a highly conserved MIZ/SUMO-E3-ligase domain and functioning in multi-protein complexes[1][3][6]. It regulates multiple transcription factors—including androgen receptor, p53, Smad3/4, and Notch1—and modulates chromatin accessibility at target gene loci[1][2][3][5][6]. ZMIZ1 plays crucial roles in cell development, proliferation, migration, angiogenesis, and immune regulation, as well as in embryonic, neural, and lymphatic vascular biology[1][2][3][5][6]. Pathogenic variants are linked to neurodevelopmental disorders, cancer, diabetes, autoimmune conditions, and vascular defects[1][2][3]. Its molecular functions make it an attractive candidate for drug development targeting hormone-dependent cancers and autoimmune diseases[3].

05

Safety considerations

Genetic perturbation can result in embryonic lethality and vascular defectsDisease-causing mutations are highly intolerant in key functional domains, leading to neurodevelopmental disabilities, abnormal cell proliferation, and tumorigenesis

Biomarkers

Mutations/variants in ZMIZ1 (notably in Alanine-rich and TPR domains) may act as biomarkers for neurodevelopmental disorders, leukemia, and other diseases
