malfunction
-
inhibition of the enzyme results in depletion of purine nucleotides

-
insulin stimulation and enzyme ATIC knockdown readily increase the level of AMP-activated protein kinase-Thr172 phosphorylation in insulin receptor complexes. Enzyme ATIC, protein-tyrosine phosphatase-like A domain-containing protein 1, and AMP-activated protein kinase knockdown affects insulin receptor internalization in HEK-293 cells

malfunction
-
the ATIC rs2372536 GG enzyme genotype is associated with improved clinical remission in juvenile idiopathic arthritis during methotrexate therapy, only one of the ATIC single nucleotide polymorphisms show any trend toward methotrexate response in an independent cohort of North American juvenile idiopathic arthritis children
metabolism
-
aminoimidazolecarboxamide ribotide transformylase is involved in the de novo purine nucleotide biosynthesis. No enzyme complex that generates 10-formyl-5,6,7,8-tetrahydrofolate and immediately channels or furnishes it to AICAR transformylase is needed because the first oxidation product of 10-formyl-5,6,7,8-tetrahydrofolate is 10-formyl-7,8-dihydrofolate that is utilized by this transformylase

the enzyme 5-aminoimidazole-4-carboxamide ribonucleotide formyltransferase/IMP cyclohydrolase plays a central role in insulin signaling and the Golgi/endosomes protein network, compartmentalization in vivo of involved enzymes in response to insulin, kinetics of the localization, overview
additional information
-
the enzyme is located at the C-terminus of the bifunctional purine-biosynthesis protein, PurH, whose N-terminus possesses IMP cyclohydrolase activity. Coupling of the two domains is essential for the catalytic process, as the AICAR Tfase reaction favours the reverse direction by itself and the irreversible cyclization of 5-formyl-aminoimidazole-4-carboxamide ribonucleotide to IMP drives formyl transfer in the forward direction
additional information
-
structure and active site of AICAR transformylase are not consistent with other enzymes that utilize 10-formyl-5,6,7,8-tetrahydrofolate. Methotrexate blockage of the AICAR transformylase process in patients with rheumatoid arthritis suggests that dihydrofolate reductase is involved and is consistent with dihydrofolate and 10-formyl-7,8-dihydrofolate being the product and substrate for AICAR transformylase
