Role and mechanism of NMNAT1 in the regulation of neural ischemic injuries by using cultured cortical neurons with oxygen-glucose deprivation of ischemic injury in vitro and mouse transient middle cerebral artery occlusion (MCAO) model of stroke in vivo, overview residues Arg11 and Arg136 are implicated in binding the phosphate groups of the ATP substrate.

Residue Arg47 does not interact with either NMN or ATP substrates directly, but is deemed to play a role in binding as it is proximal to Arg11 and Arg136, plasticity of the active site residues Arg11 and Arg136 are implicated in binding the phosphate groups of the ATP substrate.

Resistance of colorectal cancer cell-kill to Tiazofurin can be overcome by sequentially overexpressing h NMNAT2 and then facilitating the uptake of Tiazofurin by folate-tethered nanoparticles, which enter cells via folate receptors the enzyme is a target for the tumor suppressor p53, a major player in cancer signaling pathways, that is an important regulator of cellular metabolism.

Determination of an important functional role of NMNAT-2 in p53-mediated signaling.

Isozyme NMNAT1 participates in the regulation of r RNA biosynthesis, possibly by producing a local supply of NAD .

And NMNAT1 may be regulated by recruitment into complexes that consume NAD .

Heterozygous deletion of NMNAT1 in lung tumor cell lines correlates with low expression level and increased sensitivity to DNA damage.

NMNAT1 overexpression regulates neuron survival via AMPK activation, as NMNAT1 overexpression enhances AMPKactivity in OGD-treated cortical neurons, and AMPK inhibitor blocks LV-NMNAT1-induced neuroprotection in OGD-treated cortical neurons deletion of POF1 significantly lowers NAD levels and decreases the efficiency of nicotinamide riboside utilization, resistance to oxidative stress, and nicotinamide riboside-induced life span extension NMNAT1 catalyzes NAD synthesis in the last step of a salvage synthesis pathway that recycles nicotinamide (NAM) back to NAD .In NMNAT-2-knockdown cells, actinomycin D treatment does not result in enhanced immunoreactivity gain-of-function mutations in the mouse nicotinamide mononucleotide adenylyltransferase type 1, Nmnat1, produce two remarkable phenotypes: protection against traumatic axonal degeneration and reduced hypoxic brain injury, the mechanism involves the mitochondrial unfolded protein response (mito UPR) factor, penotype, overview the chromosomal region encoding the nuclear NAD synthesis enzyme NMNAT1 is frequently deleted in human cancer, which may contribute to tumor development.Knockdown of NMNAT1 enhances r RNA transcription and promotes cell death after nutrient deprivation.The enzyme is recruited into a ternary complex containing the NAD -dependent deacetylase Sir T1.NMNAT1 expression stimulates the deacetylase function of Sir T1 to deacetylate p53.

Binding structure of wild-type and mutant enzymes with NAD and NADP , detailed overview the wild-type enzyme traps a molecule of NADP in the active site.
