Recombinant human NAT8B (N-acetyltransferase 8B) protein is a genetically engineered version of a key enzyme involved in cellular acetylation processes. NAT8B belongs to the N-acetyltransferase superfamily, which catalyzes the transfer of acetyl groups from acetyl-CoA to specific substrates. This protein is predominantly expressed in the brain, kidneys, and testes, with emerging evidence linking it to neurological functions and metabolic regulation. Unlike its paralog NAT8. NAT8B shows distinct substrate specificity, potentially targeting small molecules or peptides critical for neural signaling or detoxification pathways.
The recombinant form is typically produced in bacterial or mammalian expression systems, enabling researchers to study its structure-function relationships, enzymatic activity, and interactions without interference from native cellular components. Studies suggest NAT8B may influence brain metabolism through acetylation of endogenous compounds, though its exact physiological role remains under investigation. Its dysregulation has been tentatively associated with neurological disorders and certain cancers, making it a subject of interest for biomarker discovery and therapeutic development. The availability of recombinant NAT8B protein facilitates biochemical characterization, antibody production, and high-throughput screening for modulators, accelerating research into its biological significance and potential clinical applications.
