MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is the light subunit of a cationic amino acid transporter. This sodium-independent transporter is formed when the light subunit encoded by this gene dimerizes with the heavy subunit transporter protein SLC3A2. This transporter is found in epithelial cell membranes where it transfers cationic and large neutral amino acids from the cell to the extracellular space. Defects in this gene are a cause of lysinuric protein intolerance (LPI). Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2011]
PHENOTYPE: Homozygous null mice exhibit fetal growth retardation and often die neonatally. After heavy protein ingestion, surviving adults show a metabolic derangement akin to lysinuric protein intolerance and including a lasting postnatal growth retardation, splenomegaly, hyperammonemia, and aminoaciduria.
