Predicted to enable nicotinamide-nucleotide adenylyltransferase activity and nicotinate-nucleotide adenylyltransferase activity. Predicted to be involved in NAD biosynthetic process. Predicted to act upstream of or within pyridine nucleotide biosynthetic process. Located in late endosome; synapse; and trans-Golgi network. Is expressed in alimentary system; nervous system; and sensory organ. Orthologous to human NMNAT2 (nicotinamide nucleotide adenylyltransferase 2). [provided by Alliance of Genome Resources, Apr 2022]
