Fig. 7. Model of RBFOX2 mediated regulation of insulin granule secretion in β cells.

Fig. 7

RBFOX2 (yellow) binds downstream of alternative exons to promote exon inclusion in key genes involved in insulin granule docking and exocytosis (including Stxbp1, Syt7, and Snap25). Splicing of these genes allows for proper docking and exocytosis of insulin granules. Loss of RBFOX2, results in mis-splicing of insulin granule docking and exocytosis genes. Causing a decrease in the docked pool of insulin granules and corresponding decrease in insulin secretion (created with BioRender.com).
