Exon and intron structures of CAPS2 splice variants. Alternative splicing to generate CAPS2a, 2b, 2c, 2d, 2e, and 2f cDNAs. Represented here are the p150Glued/dynactin 1 interacting domain (DID), C2 domain, PH-like domain, Munc13-1 homologous domain (MHD), and the C-terminal domain that mediates DCV binding (C-tail) . The positions of the primers used in the experiments shown in Figures 3B and C are indicated by arrows. Exons used by only one isoform are shown in black rectangles.
