A novel human nm23/nucleoside diphosphate (NDP) kinase gene, called nm23-H4, was identified by screening a human stomach cDNA library with a probe generated by amplification by reverse transcription-polymerase chain reaction. The primers were designed from publicly available database cDNA sequences selected according to their homology to the human nn23-H1 putative metastasis suppressor gene. The full-length cDNA sequence predicts a 187 amino acid protein possessing the region homologous to NDP kinases with all residues crucial for nucleotide binding and catalysis, strongly suggesting that Nm23-H4 possesses NDP kinase activity. It shares 56, 55 and 60% identity with Nm23-H1, Nm23-H2 and DR-Nm23, respectively, the other human Nm23 proteins isolated so far. Compared with these proteins, Nm23-H4 contains an additional NH2-terminal region that is rich in positively charged residues and could indicate routing to mitochondria. The nm23-H4 gene has been localised to human chromosomal band 16p13.3. The corresponding 1.2 kb mRNA is widely distributed and expressed in a tissue-dependent manner, being found at very high levels in prostate, heart, liver, small intestine and skeletal muscle tissues and in low amounts in the brain and in blood leucocytes. Nm23-H4 naturally possesses the Pro-Ser substitution equivalent to the K-pn mutation (P97S) of Drosophila.

D009701 Nucleoside-Diphosphate Kinase An enzyme that is found in mitochondria and in the soluble cytoplasm of cells. It catalyzes reversible reactions of a nucleoside triphosphate, e.g., ATP, with a nucleoside diphosphate, e.g., UDP, to form ADP and UTP. Many nucleoside diphosphates can act as acceptor, while many ribo- and deoxyribonucleoside triphosphates can act as donor. EC 2.7.4.6.

D005810 Multigene Family A set of genes descended by duplication and variation from some ancestral gene. Such genes may be clustered together on the same chromosome or dispersed on different chromosomes. Examples of multigene families include those that encode the hemoglobins, immunoglobulins, histocompatibility antigens, actins, tubulins, keratins, collagens, heat shock proteins, salivary glue proteins, chorion proteins, cuticle proteins, yolk proteins, and phaseolins, as well as histones, ribosomal RNA, and transfer RNA genes. The latter three are examples of reiterated genes, where hundreds of identical genes are present in a tandem array.
