Nicotinamide mononucleotide adenylyltransferase 1 catalyzes the formation of NAD(+) from nicotinamide mononucleotide (NMN) and ATP. Can also use the deamidated form; nicotinic acid mononucleotide (NaMN) as substrate with the same efficiency. Can use triazofurin monophosphate (TrMP) as substrate. Also catalyzes the reverse reaction, i.e. the pyrophosphorolytic cleavage of NAD(+). For the pyrophosphorolytic activity, prefers NAD(+) and NAAD as substrates and degrades NADH, nicotinic acid adenine dinucleotide phosphate (NHD) and nicotinamide guanine dinucleotide (NGD) less effectively. Fails to cleave phosphorylated dinucleotides NADP(+), NADPH and NAADP(+). Protects against axonal degeneration following mechanical or toxic insults.

Titration of the NMNAT1 antibody may be required due to differences in protocols and substrate sensitivity.

A portion of amino acids 171-201 from the human protein was used as the immunogen for the NMNAT1 antibody.

Aliquot the NMNAT1 antibody and store frozen at -20oC or colder.Avoid repeated freeze-thaw cycles.
