BET1 (Golgi vesicle membrane protein BET1) is a conserved eukaryotic protein involved in intracellular vesicular trafficking, primarily within the secretory pathway. As a member of the SNARE (Soluble NSF Attachment Protein Receptor) family, it plays a critical role in mediating membrane fusion events between transport vesicles and target organelles, particularly between the endoplasmic reticulum (ER) and the Golgi apparatus. Structurally, BET1 contains a characteristic SNARE domain that enables it to form coiled-coil complexes with other SNARE proteins (e.g., Syntaxin-5. Sec22b) to drive vesicle docking and cargo delivery.
Recombinant human BET1 is engineered via genetic expression systems (e.g., *E. coli* or mammalian cells) for in vitro studies, often fused with tags (e.g., His-tag) to facilitate purification. Its study provides insights into ER-to-Golgi transport mechanisms, protein sorting, and membrane dynamics. Dysregulation of BET1 or its partners has been implicated in diseases linked to trafficking defects, including neurodegenerative disorders and certain cancers. Research applications include reconstituting SNARE-mediated fusion assays, screening therapeutic targets for secretory pathway disorders, and analyzing vesicle-associated molecular interactions. As a tool, recombinant BET1 helps elucidate fundamental cell biology processes and potential therapeutic interventions targeting membrane trafficking pathways.
