    basic FUNCTION
  • involved in the phosphorylation of nucleoside diphosphates
  • acting as a transcription regulator for myc
  • interacting with membrane receptor and constituting a novel molecular regulatory mechanism of GPCR endocytosis
  • NME2 associates with telomerase and reduces telomerase activity, and sustained NME2 expression resulted in reduced telomere length in aggressive human cancer cells
  • novel role for NME2 as a telomere binding protein that can alter telomerase function and telomere length
  • NME1, NME2 have likely differential abilities to modulate tumorigenesis
  • NME1 and NME2 have been identified as potential canonical transcription factors that regulate gene transcription through their DNA-binding activities
  • NME1, NME2 catalyze the transfer of gamma-phosphate from nucleoside triphosphates to nucleoside diphosphates by a ping-pong mechanism involving the formation of a high-energy phosphohistidine intermediate
  • NME2, can additionally act as a protein histidine kinase
  • addition of NME1 or NME2 to DNM2 facilitates DNM2 oligomerization and increases GTPase activity, both required for vesicle scission
  • critical role of NME2 in endothelial damage via the modulation of the hexosamine biosynthesis pathway (HBP)
  • NME1, but not NME2, acts specifically to inhibit EMT and prevent the earliest stages of metastasis

    small molecule
    protein
  • interacting with ITGB1BP1
  • regulating the expression of MYC, PDGFA, and gelatinase A
  • complexing with Gbetagamma dimers contributing to G protein activation
  • interaction of HERC5 with the metastasis suppressor NME2 (Hochrainer 2008)
  • MDM2 expression causes the loss of NME2 cell motility regulatory function
  • PIWIL2 induces MYC expression by interacting with NME2 and regulates MYC-mediated tumor cell proliferation
  • NME2 interacts with PTPRS, and NME2 associates with PTPRS to elicit neurite outgrowth inhibition in response to chondroitin sulfate proteoglycans (CSPGs)
  • PGAM5 functions as a phosphohistidine phosphatase that specifically associates with and dephosphorylates the catalytic histidine on NME2
  • by dephosphorylating NME2, PGAM5 negatively regulates CD4(+) T cells by inhibiting NME2-mediated histidine phosphorylation and activation of the KCNN4
  • important role for cytoplasmic IRF6 in regulating the availability or localization of the NME1/2 complex and thus the dynamic behavior of epithelia during lip/palate development
