The human SLC7A1 protein, also known as cationic amino acid transporter 1 (CAT-1), is a member of the solute carrier family 7 (SLC7), which plays a critical role in cellular nutrient transport. Encoded by the SLC7A1 gene, this transmembrane protein primarily facilitates the uptake of cationic amino acids, such as arginine, lysine, and ornithine, via a sodium-independent mechanism. It is ubiquitously expressed, particularly in endothelial cells, hepatocytes, and immune cells, where it supports metabolic processes, nitric oxide synthesis, and cell proliferation. Structurally, SLC7A1 contains 14 putative transmembrane domains and forms a heterodimeric complex with a glycoprotein (e.g., CD98hc) for functional maturation and membrane localization.
Recombinant human SLC7A1 protein is engineered in vitro using expression systems like mammalian or insect cells to study its biological roles and interactions. Research highlights its involvement in pathological conditions, including cancer progression (e.g., tumor angiogenesis), cardiovascular diseases (via nitric oxide regulation), and immune responses. Its dysregulation is linked to impaired amino acid homeostasis and metabolic disorders. Recombinant variants are utilized in drug discovery, functional assays, and structural studies to explore therapeutic targeting, such as inhibiting arginine transport in cancer therapy or enhancing vascular function. This protein also serves as a model to investigate amino acid transporter mechanisms and their impact on cellular physiology.
