Cationic Amino Acid Transporter 2

**Definition:** A high-affinity, low capacity system y+ amino acid transporter with strong similarity to CATIONIC AMINO ACID TRANSPORTER 1. The two isoforms of the protein, CAT-2A and CAT-2B, exist due to alternative mRNA splicing. The transporter has specificity for the transport of ARGININE; LYSINE; and ORNITHINE.
