ATIC
ATIC (Bifunctional purine biosynthesis protein ATIC) is an enzyme. In the public catalogues the evidence so far is association rather than a proven role. Tied to Lung cancer.
Overview
Bifunctional enzyme that catalyses the last two steps of purine biosynthesis. Acts as a transformylase that incorporates a formyl group to the AMP analog AICAR (5-amino-1-(5-phospho-beta-D-ribosyl)imidazole-4-carboxamide) to produce the intermediate formyl-AICAR (FAICAR). Can use both 10-formyldihydrofolate and 10-formyltetrahydrofolate as the formyl donor in this reaction.
Open Targets scores its association with cancer at 0.71 (direct and indirect evidence; datatypes literature 0.93, affected pathway 0.93, genetic association 0.00, somatic mutation 0.90).

Biology
Bifunctional enzyme that catalyses the last two steps of purine biosynthesis. Acts as a transformylase that incorporates a formyl group to the AMP analog AICAR (5-amino-1-(5-phospho-beta-D-ribosyl)imidazole-4-carboxamide) to produce the intermediate formyl-AICAR (FAICAR). Can use both 10-formyldihydrofolate and 10-formyltetrahydrofolate as the formyl donor in this reaction. Also catalyses the cyclisation of FAICAR to inosine monophosphate (IMP). Is able to convert thio-AICAR to 6-mercaptopurine ribonucleotide, an inhibitor of purine biosynthesis used in the treatment of human leukaemias. Promotes insulin receptor/INSR autophosphorylation and is involved in INSR internalisation. Location: Cytoplasm, cytosol (UniProt). Locus 2q35 (HGNC).

Notes
top- Written by scripts/fetch-cancer-genes.ts from CIViC, Open Targets, IntOGen, HGNC and UniProt; the function text is UniProt's, condensed and in UK spelling. Roles: none stated by the sources. Evidence tier "association-only" is the strongest of those signals.
- Prevalence not recorded: none of the sources gives a positivity rate.
