Background Information

Glutaminase C (GAC), a splicing variant of the kidney-type glutaminase (KGA) gene, is a vital mitochondrial enzyme protein that catalyzes glutamine to glutamate. GAC is the only isoform present in the mitochondria (PMID:22228304). In a normal state, immunodecorationwith antibodies directed against GAC identified an abundant complex of 232 kDa as a tetrameric form of GAC, the DPAA can directly destructed the native tetrameric GAC complex to accumulate the unassembled one (50-90 kDa). (PMID:22493432). This antibody is specific to GAC isoform. It has no cross reaction to KGA.
