The human SLC28A1 protein, also known as concentrative nucleoside transporter 1 (CNT1), is a member of the solute carrier 28 (SLC28) family, which mediates sodium-dependent cellular uptake of nucleosides and nucleoside analogs. Encoded by the SLC28A1 gene, this transmembrane protein plays a critical role in the absorption, distribution, and metabolism of endogenous nucleosides and synthetic nucleoside-derived drugs, including anticancer agents (e.g., gemcitabine) and antiviral compounds. Predominantly expressed in epithelial tissues, the liver, and kidneys, SLC28A1 facilitates the transport of pyrimidine nucleosides and their analogs by coupling substrate translocation to the inwardly directed sodium gradient.
Recombinant human SLC28A1 protein is produced via heterologous expression systems (e.g., mammalian or insect cells) to study its structural and functional properties. Its recombinant form enables detailed investigations into substrate specificity, transport kinetics, and interactions with pharmacological agents. Research highlights its significance in drug bioavailability, cellular resistance mechanisms, and interindividual variability in drug responses due to genetic polymorphisms. Additionally, SLC28A1's role in nucleotide salvage pathways links it to cellular proliferation and energy homeostasis.
Studying recombinant SLC28A1 aids in optimizing therapeutic strategies by elucidating mechanisms underlying drug transport efficiency and toxicity, making it a focal point for developing targeted therapies in oncology and virology. Structural insights from recombinant protein studies also contribute to designing modulators to enhance drug delivery or overcome resistance.
