| Tissue Specificity | Isoform 1 and isoform 3 are detected in brain cortex. Isoform 3 is highly expressed in astrocytoma, ganglioglioma and ependymoma. Isoform 1 is highly expressed in brain and kidney, but not detected in liver. Isoform 3 is highly expressed in heart and pancreas, detected at lower levels in placenta, lung, pancreas and kidney, but is not detected in liver. Isoform 2 is expressed in cardiac and skeletal muscle. |
| Post Translational Modifications | Synthesized as a 74-kDa cytosolic precursor which is proteolytically processed by the mitochondrial-processing peptidase (MPP) via a 72-kDa intermediate to yield the mature mitochondrial 68- and 65-kDa subunits. |
| Function | Catalyzes the first reaction in the primary pathway for the renal catabolism of glutamine. Plays a role in maintaining acid-base homeostasis. Regulates the levels of the neurotransmitter glutamate, the main excitatory neurotransmitter in the brain. Isoform 2: Lacks catalytic activity. |
