CD296 is an alias for the gene, ADP-ribosyltransferase 1, in humans. Other names include: GPI-linked NAD(P)(+)--arginine ADP-ribosyltransferase 1; ADP-ribosyltransferase C2 and C3 toxin-like 1; ARTC1; Mono(ADP-ribosyl)transferase 1; CD antigen CD296; --arginine ADP-ribosyltransferase 1 ; ART2. The encoded protein is an enzyme with an amino acid length of 327 and a mass of 36.3 kDa. CD296 is a member of the Arg-specific ADP-ribosyltransferase family. This gene shares homology with other species, including: Mouse, Rat, Frog, Chicken.
