Sorting nexin 2 (SNX2), a member of the sorting nexin protein family, plays a critical role in intracellular membrane trafficking and protein sorting. Characterized by a phox homology (PX) domain, SNX2 binds to phosphatidylinositol phospholipids on membrane surfaces, facilitating its recruitment to endosomal compartments. It is involved in retrograde transport from endosomes to the trans-Golgi network (TGN) and participates in regulating endosomal sorting of transmembrane receptors, such as epidermal growth factor receptor (EGFR), to control their recycling or degradation. SNX2 also interacts with other sorting nexins (e.g., SNX1. SNX5/6) to form retromer complexes, which are essential for maintaining cellular homeostasis. Dysregulation of SNX2 has been linked to neurodegenerative diseases (e.g., Alzheimer’s) and cancer metastasis, where aberrant protein trafficking contributes to pathological progression. Recombinant human SNX2 protein, produced via heterologous expression systems (e.g., E. coli or mammalian cells), is widely used in biochemical studies to elucidate its structural motifs, binding partners, and functional mechanisms. Its applications extend to drug discovery targeting endosomal pathways and cellular transport disorders. Ongoing research continues to uncover SNX2’s role in autophagy, immune signaling, and metabolic regulation, highlighting its therapeutic potential. (Word count: 199)
