背景信息

SEC13 is a conserved eukaryotic protein integral to intracellular vesicle trafficking, primarily known for its role in the COPII (coat protein complex II) complex. This complex mediates the transport of newly synthesized proteins and lipids from the endoplasmic reticulum (ER) to the Golgi apparatus. SEC13. along with SEC31. forms the outer layer of the COPII coat, facilitating membrane curvature and vesicle budding. Structurally, SEC13 contains WD40 repeat domains that enable protein-protein interactions critical for COPII assembly.

Recombinant SEC13 refers to the protein produced via genetic engineering in heterologous expression systems (e.g., bacteria, insect cells, or mammalian cells). Its recombinant form retains functional properties, allowing researchers to study COPII dynamics, ER-Golgi trafficking mechanisms, and membrane remodeling in vitro. SEC13 is also implicated in nuclear pore complex (NPC) assembly, highlighting its dual cellular roles. Dysregulation of SEC13 has been linked to developmental disorders and diseases, such as cranio-lenticulo-sutural dysplasia and certain cancers, underscoring its biomedical relevance.

In research, recombinant SEC13 is utilized for structural studies (e.g., crystallography, cryo-EM), biochemical assays (e.g., COPII reconstitution), and drug screening targeting trafficking pathways. Its production enables exploration of COPII-related pathologies and potential therapeutic interventions. Additionally, SEC13 homologs in model organisms (e.g., yeast) have provided foundational insights into conserved trafficking mechanisms. Overall, recombinant SEC13 serves as a vital tool for dissecting cellular transport processes and their disease connections.
