SLC34A2. a member of the solute carrier 34 (SLC34) family, encodes a sodium-dependent phosphate transporter protein critical for phosphate homeostasis. Primarily expressed in lung alveolar type II cells, small intestine, and kidney, it facilitates phosphate absorption and reabsorption by cotransporting inorganic phosphate (Pi) with sodium ions across cell membranes. This transporter plays a vital role in maintaining cellular phosphate balance, essential for bone mineralization, energy metabolism, and signal transduction.
Recombinant SLC34A2 protein is engineered to study its structural and functional properties, often produced via heterologous expression systems like mammalian cells or insect cells to ensure proper post-translational modifications. Researchers utilize this protein to investigate phosphate transport mechanisms, ligand interactions, and regulatory pathways. Dysregulation of SLC34A2 is linked to pathologies such as pulmonary alveolar microlithiasis (PAM), a rare genetic disorder characterized by calcium-phosphate deposits in the lungs, often caused by loss-of-function mutations in the SLC34A2 gene.
Additionally, SLC34A2 is implicated in cancer progression, with overexpression observed in certain tumors, potentially influencing cell proliferation and metastasis. Recombinant forms enable screening of therapeutic compounds targeting phosphate dysregulation or SLC34A2-related oncogenic pathways. Its role in phosphate sensing also makes it relevant in studying metabolic disorders and developing biomarker-based diagnostics. Current research focuses on elucidating its 3D structure for drug design and exploring gene therapy approaches for PAM.
Overall, recombinant SLC34A2 serves as a key tool in bridging molecular insights with clinical applications, advancing both basic science and translational medicine.
