SLC9A3R2 (solute carrier family 9 isoform A3 regulatory factor 2), also known as NHERF2 (Na⁺/H⁺ exchanger regulatory factor 2), is a multifunctional scaffolding protein involved in regulating ion transport and cellular signaling pathways. It belongs to the NHERF family of PDZ domain-containing proteins, which play critical roles in organizing membrane-associated protein complexes. SLC9A3R2 interacts with various transmembrane receptors, ion channels, and signaling molecules through its PDZ domains, facilitating their localization, stability, and functional modulation. Notably, it binds to the cystic fibrosis transmembrane conductance regulator (CFTR), β-arrestin, and G protein-coupled receptors (GPCRs), influencing processes like pH homeostasis, receptor trafficking, and signal transduction.
Recombinant SLC9A3R2 protein is engineered for in vitro studies to elucidate its structural and functional properties. Produced via heterologous expression systems (e.g., E. coli or mammalian cell lines), it retains binding capabilities to partner proteins, enabling investigations into its role in diseases such as cancer, hypertension, and metabolic disorders. For instance, SLC9A3R2 dysregulation has been linked to tumor progression via interactions with oncogenic signaling pathways like PI3K/AKT and Wnt/β-catenin. Additionally, it modulates sodium-hydrogen exchanger activity (NHE3), impacting electrolyte balance and gut function, making it relevant in diarrheal or inflammatory bowel diseases.
Research on recombinant SLC9A3R2 also explores post-translational modifications (e.g., phosphorylation) affecting its stability and interactions. Its potential as a therapeutic target or biomarker drives ongoing studies, particularly in contexts where cellular scaffolding proteins govern disease mechanisms. The recombinant form provides a tool for high-throughput screening, structural analysis, and mechanistic studies, bridging molecular insights with translational applications.
