-
nicotinamide mononucleotide adenylyltransferase 2 (Nmat2) homozygous deletion mutants show an approximate 60% reduction of spinal motoneurons in the lumbar region and a more than 80% reduction in the sensory neurons of the dorsal root ganglion. In the absence of Nmnat2, major target organs and tissues (e.g., muscle) are not functionally innervated resulting in perinatal lethality

WldS(W258A)
the chimeric WldS protein is composed of the N-terminal 70 aa of Ufd2a/Ube4b, an ubiquitin-chain assembly factor, fused to the complete sequence of NMNAT1, the W258A mutation disrupts the NAD-synthesizing activity
C164S/C165S
-
the mutant protein is not palmitoylated (soluble), appears diffuse in the cytoplasm and does not colocalize with GM130. However, the mutant is fully active and shows even higher kcat values compared to the wild type enzyme
E198P/L217R
mutation disrupts the dimer interface, leading to a mixture of dimer and monomer in solution

expressed in Escherichia coli BL21(DE3) cells
gene Nmnat1, recombinant expression of mouse Nmnat1 non-nuclear-localized gain-of-function mutant gene (m-nonN-Nmnat1) in Caenorhabditis elegans. The transgenic enzyme provides protection from both hypoxia-induced animal death and taxol-induced axonal pathology and significantly lengthens the nematode's lifespan. Loss of function in two genes, haf-1 and dve-1, encoding mitochondrial unfolded protein response (mitoUPR) factors are identified as suppressors. M-nonN-Nmnat1 induces a transcriptional reporter of the mitoUPR gene hsp-6 and provides protection from the mitochondrial proteostasis toxin ethidium bromide. M-nonN-Nmnat1 is also protective against axonal degeneration in Caenorhabditis elegans induced by the chemotherapy drug taxol. Taxol markedly reduces basal expression of a mitoUPR reporter, the expression is restored by m-nonN-Nmnat1
transgenic mice overexpressing NMNAT1 and the mutant WldS(W258A) are generated
