**Background of NATD1 Recombinant Protein**
NATD1 (N-acetyltransferase domain-containing protein 1) is a member of the GNAT (GCN5-related N-acetyltransferase) superfamily, which is implicated in diverse biological processes through enzymatic acetylation. This protein is evolutionarily conserved and plays a role in post-translational modification, primarily targeting histones or non-histone substrates. NATD1 is suggested to regulate chromatin structure and gene expression by transferring acetyl groups from acetyl-CoA to lysine residues, influencing epigenetic signaling, DNA repair, and cell cycle progression.
Structurally, NATD1 contains a conserved acetyltransferase domain critical for substrate recognition and catalytic activity. Studies link NATD1 dysfunction to cellular stress responses and diseases, including cancer, though its precise mechanisms remain under investigation. Recombinant NATD1 protein, produced via heterologous expression systems (e.g., *E. coli* or mammalian cells), enables in vitro studies to dissect its enzymatic properties, substrate specificity, and interactions.
Research applications include enzymology assays, screening for inhibitors/activators, and exploring its role in epigenetic regulation. Its recombinant form is vital for structural studies (e.g., crystallography) to map active sites and design targeted therapies. NATD1’s involvement in acetylation pathways highlights its potential as a biomarker or therapeutic target in diseases driven by epigenetic dysregulation. Further studies aim to clarify its physiological substrates and regulatory networks in health and disease.
