"Leucine zipper proteins as emerging therapeutic regulators: structural dynamics, disease associations, and novel...

Leucine zipper proteins are transcription factors that regulate gene activity through DNA binding and creating stable pairs. They are located in particular tissues and are involved in significant processes like metabolism, immunity, and stress response. The C/EBPβ (CCAAT/Enhancer-Binding Proteins), which is predominantly active in the liver and spleen, regulates metabolism and immune activity. The GILZ (glucocorticoid-induced leucine zipper), which is located in the brain, lungs, immune cells, and reproductive system, may protect against inflammation and stress. Hormonal signals or oxidative stress may cause these proteins to be activated and transported to the nucleus to turn off or turn on the genes. The disruption of balance, such as the loss of GILZ, drives inflammation, which may cause diseases. Therapies include small molecules, peptides, or DNA decoy therapy. The selective control of these proteins via biomarker profiling and targeted tissue delivery has potential in mitigating cancer, inflammatory, and metabolic diseases.
