background:
The protein encoded by this gene is a cationic amino acid transporter and a member of the APC (amino acid-polyamine-organocation) family of transporters. The encoded membrane protein is responsible for the cellular uptake of arginine, lysine and ornithine. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2011]
Function:
Low-affinity, high capacity permease involved in the transport of the cationic amino acids (arginine, lysine and ornithine). Plays a regulatory role in classical or alternative activation of macrophages.
Subcellular Location:
Membrane.
Tissue Specificity:
Expressed at high levels in the skeletal muscle, placenta and ovary. Expressed at intermediate levels in the liver and pancreas and at low levels in the kidney and heart.
Similarity:
Belongs to the amino acid-polyamine-organocation (APC) superfamily.
Cationic amino acid transporter (CAT) (TC 2.A.3.3) family.
