Abstract
N-myristoyltransferase (NMT) is an essential eukaryotic enzyme which catalyzes the transfer of the myristoyl group to the terminal glycine residue of a number of proteins including those involved in signal transduction and apoptotic pathways. In higher eukaryotes, two isoforms of NMT have been identified (NMT1 and NMT2) which share about 76% amino acid sequence identity in humans. Protein-protein interactions of NMTs reveal that m-calpain interacts with NMT1 whereas caspase-3 interacts with NMT2. These findings reveal differential interactions of both isoforms of NMT with various signaling molecules. This minireview provides an overview of the regulation of N-myristoyltransferase by calpain and caspase systems.
n -肉豆蔻酰基转移酶(NMT)是一种重要的真核生物酶,它催化肉豆蔻酰基转移到许多蛋白质的末端甘氨酸残基,包括参与信号转导和凋亡途径的蛋白质。在高等真核生物中,已经鉴定出NMT的两个亚型(NMT1和NMT2),它们在人类中共享约76%的氨基酸序列。nmt的蛋白-蛋白相互作用表明m-calpain与NMT1相互作用,而caspase-3与NMT2相互作用。这些发现揭示了NMT的两种亚型与各种信号分子的不同相互作用。这篇综述综述了钙蛋白酶和半胱天冬酶系统对n -肉豆蔻酰基转移酶的调控。
期刊介绍:
Started in 1964, this journal publishes original research articles in the following areas: structure-function relationships of biomolecules; biomolecular recognition, protein-protein and protein-DNA interactions; gene-cloning, genetic engineering, genome analysis, gene targeting, gene expression, vectors, gene therapy; drug targeting, drug design; molecular basis of genetic diseases; conformational studies, computer simulation, novel DNA structures and their biological implications, protein folding; enzymes structure, catalytic mechanisms, regulation; membrane biochemistry, transport, ion channels, signal transduction, cell-cell communication, glycobiology; receptors, antigen-antibody binding, neurochemistry, ageing, apoptosis, cell cycle control; hormones, growth factors; oncogenes, host-virus interactions, viral assembly and structure; intermediary metabolism, molecular basis of disease processes, vitamins, coenzymes, carrier proteins, toxicology; plant and microbial biochemistry; surface forces, micelles and microemulsions, colloids, electrical phenomena, etc. in biological systems. Solicited peer reviewed articles on contemporary Themes and Methods in Biochemistry and Biophysics form an important feature of IJBB.
Review articles on a current topic in the above fields are also considered. They must dwell more on research work done during the last couple of years in the field and authors should integrate their own work with that of others with acumen and authenticity, mere compilation of references by a third party is discouraged. While IJBB strongly promotes innovative novel research works for publication as full length papers, it also considers research data emanating from limited objectives, and extension of ongoing experimental works as ‘Notes’. IJBB follows “Double Blind Review process” where author names, affiliations and other correspondence details are removed to ensure fare evaluation. At the same time, reviewer names are not disclosed to authors.
