The human EXOC6B (Exocyst complex component 6B), also known as Sec15B, is a critical subunit of the exocyst complex, an evolutionarily conserved multi-protein assembly involved in intracellular vesicle trafficking and exocytosis. This complex facilitates the tethering of secretory vesicles to the plasma membrane, enabling processes like cell polarity establishment, cytokinesis, and neurotransmitter release. EXOC6B specifically interacts with other exocyst subunits (e.g., EXOC8/Sec8) and regulatory GTPases (e.g., RalA) to mediate spatial targeting of vesicles. Structurally, it contains coiled-coil domains essential for protein-protein interactions.
Recombinant human EXOC6B protein, typically produced in bacterial or mammalian expression systems with affinity tags (e.g., His-tag), retains these functional motifs, making it valuable for in vitro studies. Researchers utilize it to investigate exocyst assembly mechanisms, vesicle transport pathways, and its role in diseases. Dysregulation of EXOC6B has been linked to cancer progression (e.g., breast, colorectal) due to altered secretory pathways promoting invasion/metastasis, and neurodevelopmental disorders associated with defective synaptic vesicle trafficking. It is also explored as a potential therapeutic target or diagnostic biomarker. Studies involving recombinant EXOC6B often employ pull-down assays, structural analyses (e.g., cryo-EM), or cellular models to dissect its molecular interactions and regulatory networks.
