ING2 (Inhibitor of Growth 2) is a tumor suppressor protein belonging to the ING family, which plays critical roles in chromatin remodeling, cell cycle regulation, apoptosis, and DNA repair. It functions as a scaffold protein that bridges histone-modifying complexes to specific chromatin regions. Structurally, ING2 contains a plant homeodomain (PHD) finger motif, enabling it to recognize histone H3K4me3 marks, and a nuclear localization signal (NLS) for subcellular targeting. By interacting with histone acetyltransferases (HATs) or histone deacetylases (HDACs), ING2 modulates chromatin structure and gene expression, particularly in stress-responsive pathways.
Recombinant ING2 protein is produced using expression systems like *E. coli* or mammalian cells, often fused with tags (e.g., His, GST) for purification and detection. Its production enables functional studies on epigenetic regulation, protein-protein interactions, and mechanisms underlying tumor suppression. Dysregulation of ING2 is linked to cancers, neurodegeneration, and aging, making it a focus for therapeutic exploration. Researchers use recombinant ING2 to investigate its binding partners, post-translational modifications (e.g., phosphorylation), and responses to DNA damage or oxidative stress. Studies also explore its role in p53-mediated apoptosis and crosstalk with oncogenic pathways. Quality validation involves SDS-PAGE, Western blotting, and activity assays to ensure proper folding and biological relevance. As an essential epigenetic regulator, recombinant ING2 serves as a valuable tool for deciphering chromatin dynamics and developing targeted therapies.
