一般描述

Research area: Cell Signaling

Nucleoside 5′-Diphosphate Kinase (NDK) is a ubiquitous housekeeping enzyme.[1] 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. [2]

应用

Nucleoside 5′-Diphosphate Kinase has been used:
  • nucleoside diphosphate kinase (NDPK) assays[3]
  • coupled NDPK-luciferase assay to determine the amounts of Ras-bound guanosine triphosphate (GTP)[4]
  • non-metastatic protein 23 (NM23) growth stimulation assay[5]
  • in a study to assess inhibition of type I Fc epsilon receptor mediated Ca2+ influx and mediator secretion in rat mucosal mast cells [6]
  • in a study to investigate protein synthesis in rabbit reticulocytes[7]

生化/生理作用

Nucleoside 5′-Diphosphate Kinases (NDKs) aid in the synthesis of nucleoside triphosphates (NTPs) by transferring a phosphate group from ATP to nucleoside diphosphates (NDPs).[1] 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.[8]

单位定义

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.

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

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 growth-factor-stimulated signal transduction, cell-surface receptors recruit PI3Ks (phosphoinositide 3-kinases) and Ras-specific GEFs (guanine nucleotide-exchange factors) to the plasma membrane, where they produce 3'-phosphorylated phosphoinositide lipids and Ras-GTP respectively. As a direct example of pathway networking, Ras-GTP also recruits and
