General annotation (Comments)

Function

Has both NAD+ glycohydrolase and ADP-ribosyltransferase activity (to a lesser extent).

Catalytic activity

NAD+ + protein-L-arginine = nicotinamide + N(omega)-(ADP-D-ribosyl)-protein-L-arginine.

NADP+ + protein-L-arginine = nicotinamide + N(omega)-((2'-phospho-ADP)-D-ribosyl)-protein-L-arginine.

NAD+ + H2O = nicotinamide + ADP-ribose.

Subcellular location

Cell membrane; Lipid-anchor › GPI-anchor.

Tissue specificity

Postthymic T-cells.

Sequence similarities

Belongs to the Arg-specific ADP-ribosyltransferase family.
