ZNF16 is a multi-C2H2 zinc finger transcription factor with dual roles in hematopoietic differentiation and nucleolar regulation. In blood cell development, ZNF16 promotes erythroid and megakaryocytic differentiation of hematopoietic stem/progenitor cells by binding to the c-KIT gene promoter and suppressing c-KIT expression, thereby activating the c-Raf/MEK/ERK/c-Jun/HEY1/GATA1 signaling cascade 1. The protein contains a trans-activation domain (amino acids 49-197) and three nuclear localization signals within its zinc finger region, enabling its nuclear function 2. Beyond hematopoiesis, ZNF16 exhibits ubiquitous tissue expression and localizes to the nucleolus in a transcription-dependent manner, where it interacts with rDNA intergenic spacer regions to promote ribosomal RNA transcription 34. ZNF16 depletion reduces cell viability across all cell lines tested, indicating essential cellular functions 3. Clinically, ZNF16 is implicated in cancer progression: elevated ZNF16 expression correlates with shorter survival in gallbladder carcinoma patients 5, and the gene promotes malignancy in tongue squamous cell carcinoma 6. ZNF16 regulates cancer-associated genes including NRAS, BIRC3, and EGFR, and participates in pathways involving extracellular matrix interactions, focal adhesions, and viral infection responses 34.
