Recombinant human SLC7A7 protein is a key component of the heterodimeric amino acid transport system, functioning as the light chain subunit of the LAT1/CD98hc (SLC3A2/SLC7A7) complex. Encoded by the *SLC7A7* gene, this transmembrane protein belongs to the solute carrier family 7 (SLC7), which mediates the sodium-independent transport of cationic amino acids such as arginine, lysine, and ornithine. It plays a critical role in intestinal absorption and renal reabsorption of these essential nutrients.
Mutations in *SLC7A7* are linked to lysinuric protein intolerance (LPI), a rare autosomal recessive disorder characterized by defective dibasic amino acid transport, leading to hyperammonemia, growth delay, and multisystem complications. Recombinant SLC7A7 protein is produced via genetic engineering in systems like mammalian cells or *E. coli* to study its structure, transport mechanisms, and interactions with partner proteins. Its recombinant form enables functional assays, drug screening, and therapeutic research for LPI.
Research also explores its potential involvement in immune modulation and cancer metabolism, as amino acid transporters influence cellular proliferation and signaling pathways (e.g., mTOR). Current studies focus on resolving its 3D structure, regulatory pathways, and designing targeted therapies to restore transport activity in LPI patients or disrupt pathological processes in malignancies.
