This enzyme catalyzes the reversible transamination between alanine and 2-oxoglutarate to generate pyruvate and glutamate and, therefore, plays a key role in the intermediary metabolism of glucose and amino acids. Serum activity levels of this enzyme are routinely used as a biomarker of liver injury caused by drug toxicity, infection, alcohol, and steatosis. A related gene on chromosome 16 encodes a putative mitochondrial alanine aminotransaminase.[provided by RefSeq, Nov 2009]. * **UniProt Summary**: Catalyzes the reversible transamination between alanine and 2-oxoglutarate to form pyruvate and glutamate. Participates in cellular nitrogen metabolism and also in liver gluconeogenesis starting with precursors transported from skeletal muscles (By similarity). {ECO:0000250}. |Aminotran 1 2| |L-alanine:2-oxoglutarate aminotransferase activity| |L-alanine catabolic process| |L-alanine metabolic process| |alanine metabolic process| |alanine catabolic process| |pyruvate family amino acid metabolic process| |pyruvate family amino acid catabolic process| |pyridoxal phosphate binding| |cellular amino acid biosynthetic process| |alpha-amino acid catabolic process| |cellular amino acid catabolic process| |alpha-amino acid metabolic process| |carboxylic acid catabolic process| |organic acid catabolic process| |carboxylic acid biosynthetic process| |organic acid biosynthetic process| |cellular amino acid metabolic process| |small molecule catabolic process| |small molecule biosynthetic process| |carboxylic acid metabolic process| |oxoacid metabolic process| |organic acid metabolic process| |organonitrogen compound catabolic process| |organonitrogen compound biosynthetic process| |small molecule metabolic process| |organic substance catabolic process| |cellular catabolic process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp246|UM0011500 10μM R05 exp246]]|1.71| |[[:results:exp223|Cabazitaxel 0.001μM R05 exp223]]|1.87| |[[:results:exp152|SGC2043 10μM R03 exp152]]|1.89| |[[:results:exp15|Cycloheximide 0.2μM R00 exp15]]|1.93| ^Gene^Correlation^ |[[:human genes:p:prim1|PRIM1]]|0.443| |[[:human genes:d:dtl|DTL]]|0.4| Global Fraction of Cell Lines Where Essential: 0/726 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|0/1| |909776.0|0/1| |bile duct|0/28| |blood|0/28| |bone|0/25| |breast|0/33| |central nervous system|0/56| |cervix|0/4| |colorectal|0/17| |esophagus|0/13| |fibroblast|0/1| |gastric|0/15| |kidney|0/21| |liver|0/20| |lung|0/75| |lymphocyte|0/14| |ovary|0/26| |pancreas|0/24| |peripheral nervous system|0/16| |plasma cell|0/15| |prostate|0/1| |skin|0/24| |soft tissue|0/7| |thyroid|0/2| |upper aerodigestive|0/22| |urinary tract|0/29| |uterus|0/5| == Essentiality in NALM6 == * **Essentiality Rank**: 2501 * **Expression level (log2 read counts)**: 0.15 {{:chemogenomics:nalm6 dist.png?nolink |}}
