Component of the purine nucleotide cycle (PNC), which interconverts IMP and AMP to regulate the nucleotide levels in various tissues, and which contributes to glycolysis and ammoniagenesis. Catalyzes the first commited step in the biosynthesis of AMP from IMP.
Predominantly expressed in skeletal muscle and heart, as well as in several hematopoietic cell lines and solid tumors.
Purine metabolism; AMP biosynthesis via de novo pathway; AMP from IMP: step 1/2.
Belongs to the adenylosuccinate synthetase family.
