Here’s a concise description of recombinant human SLC46A2 protein:
Solute Carrier Family 46 Member 2 (SLC46A2) is a transmembrane protein encoded by the SLC46A2 gene, belonging to the SLC46 family of proton-coupled transporters. It is primarily expressed in immune tissues, intestinal epithelial cells, and the placenta. While its exact physiological role remains under investigation, SLC46A2 is proposed to function as a transporter for small molecules, potentially including histidine, folate derivatives, or other substrates critical for cellular metabolism and immune regulation. Structural studies reveal it contains 12 predicted transmembrane domains and forms a trimeric configuration for substrate transport.
Recombinant human SLC46A2 protein is engineered using mammalian expression systems (e.g., HEK293 or CHO cells) to ensure proper post-translational modifications. This biotechnologically produced version enables functional studies, including substrate specificity assays, inhibitor screening, and structural characterization. Research implicates SLC46A2 in autoimmune disorders and cancer progression, with emerging evidence linking its polymorphisms to altered drug responses. Its recombinant form serves as a vital tool for developing diagnostic antibodies and exploring therapeutic strategies targeting nutrient transport pathways in malignancies or inflammatory diseases. Current challenges include elucidating its full spectrum of endogenous substrates and resolving its 3D structure for rational drug design.
