Zinc finger and BTB domain-containing protein 11 (ZBTB11)

Zinc finger and BTB domain-containing protein 11 (ZBTB11) is a transcription factor characterized by an N-terminal BTB domain—known for mediating protein-protein interactions—and tandem C-terminal zinc finger motifs responsible for sequence-specific DNA binding. ZBTB11 regulates the transcription of nuclear genes involved in mitochondrial biogenesis, especially those in respiratory complex I and the mitoribosome, by facilitating the locus-specific recruitment of nuclear respiratory factor 2 (NRF-2/GABP). Loss-of-function mutations in ZBTB11 are causative for hereditary intellectual disability, typically presenting with mitochondrial defects and impaired neuronal development. Additionally, ZBTB11 contributes to the regulation of hematopoietic lineage commitment (notably, neutrophil development via the PU.1-ZBTB11-p53 axis) and is implicated in the pathogenesis, progression, and metastatic spread of various cancers as both a prognostic biomarker and a potential therapeutic target. ZBTB11's functions suggest that drugs targeting this factor could influence mitochondrial homeostasis, stemness, DNA repair, and invasion, but no specific inhibitors have yet entered clinical practice. The broad essentiality of ZBTB11 in gene regulation and mitochondrial physiology presents significant therapeutic challenges and safety concerns in any future targeting strategy.

Not established for drugs (no approved/identified drugs directly targeting ZBTB11). Potential mechanisms (if drugs developed): modulation of ZBTB11-mediated transcriptional control, restoration or inhibition of nuclear respiratory factor 2 recruitment, or interference with SET-ZBTB11 oncogenic complex
