    Summary
    Predicted to enable glutaminase activity. Predicted to be involved in glutamate biosynthetic process and glutamine catabolic process. Predicted to act upstream of or within reactive oxygen species metabolic process and regulation of apoptotic process. Located in mitochondrion. Is expressed in several structures, including alimentary system; limb; nervous system; skeleton; and urinary system. Orthologous to human GLS2 (glutaminase 2).

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
