    basic FUNCTION
  • bifunctional enzymes catalysing the last two steps in de novo purine biosynthesis, second last step 5-aminoimidazole-4-carboxamide ribonucleotide formyltransferase (AICARFT), this enzyme catalyses the formylation of AICAR with 10-formyl-tetrahydrofolate to yield FAICAR and tetrahydrofolate
  • enhances insulin sensitivity and reverses insulin resistance under several conditions in skeletal muscles
  • potential anti diabetic drug, significantly counteracted the negative effects of beta-hydroxybutyrate (BOH) on insulin action
  • ATIC acts as an oncogenic gene that promotes survival, proliferation and migration by targeting AMPK-MTOR-S6 K1 signaling
  • bifunctional protein enzyme, catalyzing the last two steps of the de novo purine biosynthetic pathway

    RNA
    small molecule
    protein
  • appeared to exert its effect on insulin-mediated glucose uptake by enhancing phosphorylation of the Akt substrate TBC1D4
  • ATIC, which is a rate-limiting enzyme in the de novo purine biosynthesis pathway, and PTPLAD1 are associated with insulin receptor (INSR) internalization
  • ATIC suppresses AMPK activation, thus activates MTOR-S6 K1-S6 signaling and supports growth and motility activity of HCC cells
  • IL7 stimulation induced the phosphorylation of the proteins STIP1, ATIC and HNRNPH, involved in pathways related to survival, proliferation and gene expression, respectively, and increased the phosphorylation of CRKL
  • OSBPL2 was found to interact with ATIC, key activator of AMPK
  • cell & other
    REGULATION
    Other ALK-mediated ATIC phosphorylation enhanced its enzymatic activity, dampening the methotrexate-mediated transformylase activity inhibition
