ART4/CD297 is a predicted NAD+ ADP-ribosyltransferase that exhibits biased expression in tissues such as the adrenal gland and thymus. As an ortholog of human ART4, it is involved in peptidyl arginine ADP ribosylation. ART4/CD297 Protein, Rat (HEK293, His) is the recombinant rat-derived ART4/CD297 protein, expressed by HEK293 , with C-His labeled tag.
