CC -!- FUNCTION: Nicotinamide/nicotinate-nucleotide adenylyltransferase that
CC acts as an axon maintenance factor (By similarity). Catalyzes the
CC formation of NAD(+) from nicotinamide mononucleotide (NMN) and ATP. Can
CC also use the deamidated form; nicotinic acid mononucleotide (NaMN) as
CC substrate but with a lower efficiency. Cannot use triazofurin
CC monophosphate (TrMP) as substrate. Also catalyzes the reverse reaction,
CC i.e. the pyrophosphorolytic cleavage of NAD(+). For the
CC pyrophosphorolytic activity prefers NAD(+), NADH and NaAD as substrates
CC and degrades nicotinic acid adenine dinucleotide phosphate (NHD) less
CC effectively. Fails to cleave phosphorylated dinucleotides NADP(+),
CC NADPH and NaADP(+) (By similarity). Axon survival factor required for
CC the maintenance of healthy axons: acts by delaying Wallerian axon
CC degeneration, an evolutionarily conserved process that drives the loss
CC of damaged axons (By similarity). {ECO:0000250|UniProtKB:Q8BNJ3,

CC (nicotinamide-riboside-5')-tetraphosphate (Np4AD).

CC {ECO:0000250|UniProtKB:Q9BZQ4}. Cell projection, axon
CC {ECO:0000250|UniProtKB:Q8BNJ3}. Note=Delivered to axons with Golgi-
CC derived cytoplasmic vesicles. {ECO:0000250|UniProtKB:Q8BNJ3}.
CC -!- PTM: Degraded in response to injured neurite. Degradation is probably
CC caused by ubiquitination by MYCBP2 (By similarity). Ubiquitinated on
CC threonine and/or serine residues by MYCBP2; consequences of threonine
CC and/or serine ubiquitination are however unclear (By similarity).
CC {ECO:0000250|UniProtKB:Q8BNJ3, ECO:0000250|UniProtKB:Q9BZQ4}.
CC -!- PTM: Palmitoylated; palmitoylation is required for membrane
CC association. {ECO:0000250|UniProtKB:Q8BNJ3}.
CC -!- SIMILARITY: Belongs to the eukaryotic NMN adenylyltransferase family.
CC {ECO:0000305}.
