**Background of STX12 Recombinant Protein**
STX12 (Syntaxin-12), a member of the SNARE (soluble N-ethylmaleimide-sensitive factor attachment protein receptor) protein family, plays a critical role in intracellular membrane trafficking and vesicle fusion processes. It is primarily localized to early endosomes and the trans-Golgi network, where it mediates the docking and fusion of transport vesicles with target membranes. STX12 interacts with other SNARE proteins, such as VAMP4 and SNAP23. to form functional complexes essential for maintaining cellular compartmentalization, cargo sorting, and signal transduction. Dysregulation of STX12 has been implicated in neurological disorders, cancer progression, and metabolic diseases, underscoring its biological significance.
Recombinant STX12 protein is engineered using heterologous expression systems, such as *E. coli* or mammalian cell lines, to produce high-purity, functional protein for research applications. The recombinant form typically retains key structural domains, including the SNARE motif and transmembrane region, enabling in vitro studies on its binding partners, regulatory mechanisms, and role in vesicle dynamics. Researchers utilize STX12 recombinant protein to investigate its involvement in autophagy, receptor recycling, and synaptic transmission, as well as to screen for therapeutic agents targeting SNARE-mediated pathways. Its application extends to structural biology, antibody development, and disease modeling, providing a versatile tool for decoding membrane trafficking networks and their pathological disruptions.
