ZNF516 (Zinc Finger Protein 516): ZNF516 is a transcriptional regulator that can act as either a repressor or activator in gene expression pathways controlling cell differentiation, proliferation, and apoptosis. It plays a critical role in cardiac development and function, with dysregulation linked to cardiovascular diseases. ZNF516 has also been associated with tumor suppression, making it a potential target in cancer therapy and an important factor in maintaining cellular homeostasis.
