STXBP3 Protein, Human (sf9, His-GST)

STXBP3 protein, together with STX4 and VAMP2, may promote insulin-dependent GLUT4 movement and fusion of GLUT4-containing vesicles with the adipocyte cell surface. It interacts directly with DOC2B on the cell membrane (excluding STX4 interaction) and regulates glucose-stimulated insulin secretion. STXBP3 Protein, Human (sf9, His-GST) is the recombinant human-derived STXBP3 protein, expressed by Sf9 insect cells , with N-His, N-GST labeled tag. The total length of STXBP3 Protein, Human (sf9, His-GST) is 592 a.a., with molecular weight of ~95.6 kDa.

The STXBP3 protein, in conjunction with STX4 and VAMP2, potentially functions in the insulin-dependent movement of GLUT4 and the docking/fusion of intracellular GLUT4-containing vesicles with the cell surface in adipocytes. Additionally, STXBP3 interacts with DOC2B directly at the cell membrane, excluding interaction with STX4, thereby regulating glucose-stimulated insulin secretion. Furthermore, STXBP3 engages in interaction with STX4, indicating its involvement in diverse cellular processes, particularly those related to vesicle trafficking and insulin-responsive glucose transport in adipocytes. These molecular associations underscore the multifaceted role of STXBP3 in cellular dynamics and insulin-regulated pathways.
