ZNF541 is a zinc finger transcription factor essential for male fertility and meiotic progression in spermatocytes [UniProt]. As a transcriptional regulator, ZNF541 activates expression of genes required for pachytene stage advancement during spermatogenesis while maintaining repression of pre-pachytene programs, including meiotic double-strand break (DSB) formation genes [UniProt]. This dual regulatory role ensures proper meiosis progression by suppressing aberrant DSB formation after mid-pachytene [UniProt]. ZNF541 functions through transcriptional corepressor activity and histone deacetylase complex interactions [GO Annotations]. Beyond its canonical role in reproduction, ZNF541 appears relevant to cancer biology. In cervical cancer, ZNF541 was identified as an upstream modulator of genes differentially expressed in HPV16-positive tissues, suggesting involvement in HPV-mediated oncogenic transcriptional programs 1. Similarly, in head and neck squamous cell carcinoma, ZNF541 was among genes significantly associated with natural killer cell infiltration and patient survival outcomes 2. Expression analysis revealed ZNF541 as differentially expressed between HPV-positive and HPV-negative head and neck cancers 3. Additionally, ZNF541 haploinsufficiency through 19q13.32 microdeletion contributes to developmental abnormalities including facial dysmorphia, neurological defects, and orofacial clefting 4, indicating broader developmental significance beyond spermatogenesis.
