FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a mitochondrial alanine transaminase, a pyridoxal enzyme that catalyzes the reversible transamination between alanine and 2-oxoglutarate to generate pyruvate and glutamate. Alanine transaminases play roles in gluconeogenesis and amino acid metabolism in many tissues including skeletal muscle, kidney, and liver. Activating transcription factor 4 upregulates this gene under metabolic stress conditions in hepatocyte cell lines. A loss of function mutation in this gene has been associated with developmental encephalopathy. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2015]
PHENOTYPE: Mice homozygous for a knock-out allele exhibit hypoactivity, reduced postnatal brain growth, various metabolic defects in pathways involving amino acid metabolism, the TCA cycle and neuroprotective mechanisms, and premature death. [provided by MGI curators]
