DESCRIPTION

Also known as GLSK_HUMAN, GLS, GLS1, KIAA0838. 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 (PubMed:30575854, PubMed:30239721, PubMed:30970188)., Lacks catalytic activity. Homotetramer, dimer of dimers (PubMed:22538822, PubMed:26988803, PubMed:28526749, PubMed:29317493). The tetramers can assemble into rod-like oligomers (in vitro), but the physiological significance of this is not clear (By similarity). Interacts with RAF1 and MAP2K2 (PubMed:22538822). Interacts with ATCAY; the interaction is direct and may control GLS localization, negatively regulating its activity.
