AbstractN-myristoyltransferase 1 (NMT1) is an indispensable eukaryotic enzyme that catalyses the transfer of myristoyl groups to the amino acid terminal residues of numerous proteins. This catalytic process is required for the growth and development of many eukaryotes and viruses. Elevated expression and activity of NMT1 is observed to varying degrees in a variety of tumour types (e.g. colon, lung and breast tumours). Furthermore, an elevated level of NMT1 in tumours is associated with poor survival. Therefore, a relationship exists between NMT1 and tumours. In this review, we discuss the underlying mechanisms by which NMT1 is associated with tumour development from the perspective of oncogene signalling, involvement in cellular metabolism, and endoplasmic reticulum stress. Several NMT inhibitors used in cancer treatment are introduced. The review will provide some directions for future research.Key MessagesElevated expression and activity of NMT1 is observed to varying degrees in a variety of tumour types which creates the possibility of targeting NMT1 in tumours.NMT1-mediated myristoylation plays a pivotal role in cancer cell metabolism and may be particularly relevant to cancer metastasis and drug resistance. These insights can be used to direct potential therapeutic avenues for NMT1 inhibitors.
