General annotation (Comments)

Function

Plays an important role in the regulation of glutamine catabolism. Promotes mitochondrial respiration and increases ATP generation in cells by catalyzing the synthesis of glutamate and alpha-ketoglutarate. Increases cellular anti-oxidant function via NADH and glutathione production By similarity.

Catalytic activity

L-glutamine + H2O = L-glutamate + NH3.

Subunit structure

Interacts with the PDZ domain of the syntrophin SNTA1. Interacts with the PDZ domain of TAX1BP3 By similarity.

Subcellular location

Mitochondrion.

Tissue specificity

Liver specific.

Sequence similarities

Belongs to the glutaminase family.

Contains 2 ANK repeats.

Sequence caution

The sequence AAH89776.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened.
