The majority of L-Arg transport is mediated by System y+, although several other carriers have been kinetically defined. System y+ cationic amino acid transport is mediated by proteins encoded by a family of genes, Cat1, Cat2, and Cat3. High affinity L-arginine transport was investigated in embryonic fibroblast cells derived from Cat1 knockout mice that lack functional Cat1. Both wild type and knockout cells transport arginine with comparable Km and Vmax. However, the apparent affinity for lysine transport was 2.4 times lower in Cat1(-/-) cells when compared with wild type cells, a property characteristic of Cat3-mediated transport. Northern analysis-documented Cat2 mRNA increased 2-fold, whereas Cat3 mRNA levels increased 11-fold in Cat1(-/-) relative to Cat1(+/+) cells. The low affinity Cat2a mRNA was not detectably expressed in these cells. Even though Cat3 expression is normally limited to adult brain, there was a large increase in the amount of Cat3 protein present at the plasma membrane of Cat1(-/-) embryonic fibroblast cells. These results suggest that Cat3 compensates for the loss of functional Cat1 in cells derived from Cat1 knockout mice and mediates the majority of high affinity arginine transport."xsd:string |
