Summary: Enables L-arginine transmembrane transporter activity. Involved in L-arginine transmembrane transport and regulation of macrophage activation. Acts upstream of or within several processes, including macrophage activation; nitric oxide biosynthetic process; and nitric oxide production involved in inflammatory response. Located in membrane. Is expressed in several structures, including alimentary system; brain; genitourinary system; immune system; and respiratory system. Orthologous to human SLC7A2 (solute carrier family 7 member 2).

In wild-type mice exposed to hyperoxia, the exhaled nitric oxide (exNO) was twofold greater than in wild-type mice exposed to normoxia ( P < 0.005), whereas in slc7a2(-/-) mice there was no significant difference between exNO in animals exposed to hyperoxia or normoxia ( P = 0.95). These results are consistent with our hypothesis that lack of CAT-2 protects mice from acute lung injury.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
