E. coli-derived recombinant human protein (amino acids M1-F658) was used as the immunogen for the CAT2 antibody.
Cationic amino acid transporter 2 (CAT2) is a protein that in humans is encoded by the SLC7A2 gene. 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.
