Rabbit 5-aminoimidazole-4-carboxamide ribonucleotide formyltransferase/IMP cyclohydrolase Polyclonal Antibody | anti-ATIC antibody
Rabbit anti-human 5-aminoimidazole-4-carboxamide ribonucleotide formyltransferase/IMP cyclohydrolase polyclonal Antibody
NCBI and Uniprot Product Information
NCBI Description
This gene encodes a bifunctional protein that catalyzes the last two steps of the de novo purine biosynthetic pathway. The N-terminal domain has phosphoribosylaminoimidazolecarboxamide formyltransferase activity, and the C-terminal domain has IMP cyclohydrolase activity. A mutation in this gene results in AICA-ribosiduria. [provided by RefSeq, Sep 2009]
Uniprot Description
ATIC: Bifunctional enzyme that catalyzes 2 steps in purine biosynthesis. Defects in ATIC are the cause of AICAR transformylase/IMP cyclohydrolase deficiency (AICAR). A neurologically devastating inborn error of purine biosynthesis. Patients excrete massive amounts of AICA-riboside in the urine and accumulate AICA- ribotide and its derivatives in erythrocytes and fibroblasts. AICAR causes profound mental retardation, epilepsy, dysmorphic features and congenital blindness. Belongs to the PurH family.
