| Function | Catalyzes the formation of NAD(+) from nicotinamide mononucleotide (NMN) and ATP. Can also use the deamidated form; nicotinic acid mononucleotide (NaMN) as substrate but with a lower efficiency. Cannot use triazofurin monophosphate (TrMP) as substrate. Also catalyzes the reverse reaction, i.e. the pyrophosphorolytic cleavage of NAD(+). For the pyrophosphorolytic activity prefers NAD(+), NADH and NaAD as substrates and degrades nicotinic acid adenine dinucleotide phosphate (NHD) less effectively. Fails to cleave phosphorylated dinucleotides NADP(+), NADPH and NaADP(+). {ECO:0000269|PubMed:16118205, ECO:0000269|PubMed:17402747}. |
| Subcellular Location | Cytoplasm {ECO:0000269|PubMed:16118205}. Golgi apparatus {ECO:0000269|PubMed:16118205}. |
| Tissue Specificity | Highly expressed in brain, in particular in cerebrum, cerebellum, occipital lobe, frontal lobe, temporal lobe and putamen. Also found in the heart, skeletal muscle, pancreas and islets of Langerhans. {ECO:0000269|PubMed:12359228, ECO:0000269|PubMed:14516279, ECO:0000269|PubMed:16118205}. |
