General description

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.

Application

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

Biochem/physiol Actions

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.

Unit Definition

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 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.
