    SUBCELLULAR LOCALIZATION     intracellular
    basic FUNCTION
  • pyrimidine biosynthetic pathway, involved in the phosphorylation of nucleoside diphosphates
  • selectively regulates the PRKAA1, independently of the AMP concentration such that the manipulation of NME1 nucleotide trans-phosphorylation activity to generate ATP enhanced the activity of PRKAA1
  • involved in the regulation of many cellular processes as well as in tumor metastasis
  • involved in epidermal homeostasis which depends on a tight regulation of the levels of NME1 isoforms
  • can negatively regulate cell migration and tumor metastasis by modulating the activity of CDC42 and possibly other Rho family members through interaction with MCF2
  • having a 3prime-5prime exonuclease activity necessary for metastasis suppressor function
  • tumor metastasis suppressor, which functions as a nucleoside-diphosphate kinase converting nucleoside diphosphates to nucleoside triphosphates with an expense of ATP
  • may have a role in the regulation of cell cycle and apoptosis in human B-cells
  • loss of NME1, an event suspected to promote metastasis, may additionally function at an earlier stage of tumor development to drive the acquisition of chromosomal instability
  • critical for control of cell-cell adhesion and cell migration at early stages of the invasive program in epithelial cancers, orchestrating a barrier against conversion of in situ carcinoma into invasive malignancy
  • critical role for NME1 isoforms in limiting mutagenesis and suppressing UV radiation -induced melanomagenesis
  • exists in a functional cellular complex with PRKAA1 and CFTR in airway epithelia, and its catalytic function is required for the PRKAA1-dependent regulation of CFTR
    a component
  • complexing with SCS(succinyl-coA-synthetase)
    small molecule
  • MEN1, SCS
  • interacting with TUBB, TUBG1, VIM
  • interaction partner of PRUNE
  • IFI16 and NME1 are simultaneously bound to the same DNA fragments, suggesting their common involvement in the reduced development of some tumors
  • TXNRD1 is an interacting protein of NME1, and it binds specifically to oxidized NME1
  • TSLP might downregulate NME1 expression via STAT3 signaling pathway, affecting TIMP1 expression in influencing trophoblast invasion
  • NME1 enhanced ALDOC transcription, evidenced by increased expression of ALDOC pre-mRNA and activity of an ALDOC promoter-luciferase module
  • cell & other
    inhibited by of NME1 expression by TSLP was completely abrogated by STAT3 inhibitor
    Other key enzymatic and metastasis suppressor functions of NME1 are regulated by oxido-reduction of its Cys109
