Opis ogólny

Research area: Cell Signaling

Nucleoside 5′-Diphosphate Kinase (NDK) is a ubiquitous housekeeping enzyme. Nucleoside Diphosphate Kinase exists in two isoforms in eukaryotic cells, NDK-A and NDK-B. These enzymes are found expressed both in the mitochondria and the cytoplasm.

Zastosowanie

Nucleoside 5′-Diphosphate Kinase has been used:
  • nucleoside diphosphate kinase (NDPK) assays
  • coupled NDPK-luciferase assay to determine the amounts of Ras-bound guanosine triphosphate (GTP)
  • non-metastatic protein 23 (NM23) growth stimulation assay
  • in a study to assess inhibition of type I Fc epsilon receptor mediated Ca2+ influx and mediator secretion in rat mucosal mast cells
  • in a study to investigate protein synthesis in rabbit reticulocytes

Działania biochem./fizjol.

Nucleoside 5′-Diphosphate Kinases (NDKs) aid in the synthesis of nucleoside triphosphates (NTPs) by transferring a phosphate group from ATP to nucleoside diphosphates (NDPs). NDKs provide NTPs for nucleic acid synthesis, cytidine 5′-triphosphate (CTP) for lipid synthesis, uridine 5′-triphosphate (UTP) for polysaccharide synthesis, and guanosine triphosphate (GTP) for protein elongation, signal transduction, and microtubule polymerization.

Definicja jednostki

One unit will convert 1.0 μmole each of TDP and ATP to TTP and ADP per min at pH 7.6 at 25 °C in a coupled system with PK/LDH.

The family of Nm23/NDPK (nucleoside diphosphate kinase) proteins regulates a vast variety of cellular processes and, therefore, participates in important physiological events like proliferation, differentiation, molecular transport, and apoptosis. The majority of experimental data concerning this gene family has been

In textbooks of biochemistry, nucleoside diphosphate conversion to a triphosphate by nucleoside diphosphate 'kinases' (NDPKs, also named NME or NM23 proteins) merits a few lines of text. Yet this essential metabolic function, mediated by a multimeric phosphotransferase protein, has effects

Anoxia-tolerant plant tissues synthesize a number of proteins during anoxia, in addition to the 'classical anaerobic proteins' involved in glycolysis and fermentation. The present study used a model system of rice coleoptile tips to elucidate patterns of protein synthesis in

Type I Fc epsilon receptor (Fc epsilon RI) mediated Ca2+ uptake and secretion of rat serosal mast cells have been shown to be inhibited by disodium 1,3-bis [(2'-carboxylatochromon-5'-yl) oxy]-2-hydroxypropane (disodium cromoglycate, DSCG), which is widely employed in the treatment of

The MUC1 protein is aberrantly expressed on many solid tumor cancers. In contrast to its apical clustering on healthy epithelial cells, it is uniformly distributed over cancer cells. However, a mechanistic link between aberrant expression and cancer has remained elusive.
