| Function | Mitochondrial arginine transporter that catalyzes the counter-exchange of arginine with lysine, ornithine, arginine and histidine. Substrate preference in reconstituted proteoliposomes is arginine > lysine > ornithine > histidine. May be involved in the delivery of arginine, released from seed reserves, to mitochondrial arginase and the export of ornithine. {ECO:0000269|PubMed:12631327, ECO:0000269|PubMed:16730327}. |
| Subcellular Location | Mitochondrion inner membrane {ECO:0000250}; Multi-pass membrane protein {ECO:0000250}. |
| Tissue Specificity | High expression in flowers and siliques. Lower expression in leaves and stems. {ECO:0000269|PubMed:12631327}. |
