the enzyme can be used for protein N-myristoylation as a tag labeling technique in recombinant expresssion systems. CaNMT is an effective tool for in vitro and in vivo transfer of an azide-modified acid to the N-terminus of a polypeptide derived from a species entirely unrelated to Candida albicans
recombinant expression of N-myristoylated proteins in Escherichia coli can be achieved by co-expressing N-myristoyltransferase and supplementing the growth medium with myristic acid. Undesired incorporation of the 12-carbon fatty acid lauric acid can also occur, leading to heterogeneous samples. A strategy for obtaining lauryl-free samples of myristoylated proteins in both rich and minimal media
since myristoylation has a central role in virus maturation and oncogenesis, specific NMT inhibitors might lead to potent antivirus and anticancer agents
both NMT1 and hnRNP A2/B1 may take part in the regulation of HIV-1 RNA expression through their mutual opposite effects on the viral RNA expression in HIV-1-producing cells
infection of HeLa cells with coxsackievirus B3 in the presence of NMT inhibitor DDD85646 decreases capsid protein VP0 acylation at least 100fold, resulting in a defect both early and late in virus morphogenesis, which diminishes the yield of viral progeny by about 90%. Virus particles still produced consist mainly of provirions containing RNA and uncleaved VP0 and, to a substantially lesser extent, of mature virions with cleaved VP0. Neither parechoviruses nor kobuviruses are affected by DDD85646. Individual knockout of the genes encoding the two human NMT isozymes in haploid HAP1 cells demonstrates the pivotal role for isoform NMT1, with little contribution by NMT2
pharmacological inhibition of host cell N-myristoylation rapidly and completely prevents rhinoviral replication without inducing cytotoxicity. Inhibition of cotranslational myristoylation virus-encoded protein VP0 by inhibitor 1-(5-[3,4-difluoro-2-[2-(1,3,5-trimethyl-1H-pyrazol-4-yl)ethoxy]phenyl]-1-methyl-1H-indazol-3-yl)-N,N-dimethylmethanamine potently blocks a key step in viral capsid assembly, delivering low nanomolar antiviral activity against multiple rhinovirus strains, poliovirus and foot-and-mouth disease virus, and protection of cells against virus-induced killing, highlighting the potential of host myristoylation as a drug target in picornaviral infections
upon inhibition of mTOR by treating MCF7 cells with rapamycin, the expression of NMT1 increases with rapamycin treatment over the period of time with a concomitant decrease in mTOR phosphorylation. Activated mammalian target of rapamycin (mTOR) is positively associated with overall survival and recurrence free survival in ER positive breast cancer patients who were later treated with tamoxifen
