This gene product belongs to the nicotinamide-nucleotide adenylyltransferase (NMNAT) enzyme family, members of which catalyze an essential step in the nicotinamide adenine dinucleotide (NAD (NADP)) biosynthetic pathway. Unlike the other human family member, which is localized to the nucleus, and is ubiquitously expressed; this enzyme is cytoplasmic, and is predominantly expressed in the brain. Two transcript variants encoding different isoforms have been found for this gene.[7]

Loss of NMNAT2 initiates Wallerian degeneration.[8]

The catechin epigallocatechin gallate found in tea can activate NMNAT2 by more than 100%.[9]
