NARG2 (N-acetyltransferase-related Gene 2), also known as NAT10 or ARD1. is a member of the GNAT (Gcn5-related N-acetyltransferase) superfamily involved in diverse cellular processes. It encodes a protein with both lysine acetyltransferase and RNA acetyltransferase activities, playing roles in chromatin remodeling, transcriptional regulation, and ribosome biogenesis. Human NARG2 is ubiquitously expressed and localized in the nucleus/nucleolus. Studies suggest its involvement in cell cycle progression, DNA damage response, and stem cell maintenance through acetylation-dependent pathways. Dysregulation of NARG2 has been linked to cancers, neurodegenerative diseases, and aging-related pathologies.
Recombinant human NARG2 protein is typically produced using E. coli or mammalian expression systems, enabling functional studies of its enzymatic mechanisms and interactome. The purified protein facilitates in vitro acetylation assays, structural analysis (e.g., crystallography/Cryo-EM), and drug discovery targeting its catalytic domains. Recent research highlights its potential as a therapeutic target, particularly in chemoresistant cancers where NARG2 overexpression promotes survival. Technical challenges include maintaining post-translational modifications and solubility during purification. Current investigations focus on its non-canonical roles in rRNA modification and emerging connections to cellular stress adaptation.
