Protein

Cationic amino acid transporter 2

Gene

Slc7a2

Organism
Rattus norvegicus (Rat)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at transcript leveli

Functioni

Functions as permease involved in the transport of the cationic amino acids (arginine, lysine and ornithine). The affinity for its substrates differs between isoforms created by alternative splicing. May play a role in classical or alternative activation of macrophages via its role in arginine transport.By similarity
