**Background of Recombinant Human STX3A Protein**
Recombinant human STX3A (Syntaxin 3A) protein is a genetically engineered form of the STX3A protein, a member of the SNARE (soluble N-ethylmaleimide-sensitive factor attachment protein receptor) family. Syntaxin 3A plays a critical role in intracellular membrane trafficking and vesicle fusion, particularly in polarized cells such as epithelial and neuronal cells. It localizes to the apical plasma membrane, where it mediates the docking and fusion of transport vesicles, essential for processes like epithelial cell polarity, neurotransmitter release, and the regulation of ion channels.
STX3A is implicated in cellular functions ranging from membrane repair to the secretion of digestive enzymes and mucins. Mutations or dysregulation of STX3A are linked to pathologies such as microvillus inclusion disease (MVID), a rare congenital enteropathy, highlighting its importance in gastrointestinal physiology. Recombinant STX3A is typically produced in heterologous expression systems (e.g., *E. coli* or mammalian cells) for research applications, enabling studies on its molecular interactions, structural biology, and role in disease mechanisms. It serves as a vital tool for dissecting SNARE complex dynamics, screening therapeutic agents, and exploring gene therapy approaches for STX3A-related disorders.
