From: CDC2/SPDY transiently associates with endoplasmic reticulum exit sites during oocyte maturation
CDC2 associates with SPDY at ERES. (A-C) 0 h GV stage oocyte labeled for CDC2 (A, green), DNA (A, blue), and SPDY (B, red). Both CDC2 and SPDY localize to the same cortical domain (C). Note that the center of this oocyte is dented (the area that contains the arrow) causing the structure to appear in the middle of the oocyte, whereas it is located in the cortex. (D-F) 0 h GV stage oocyte stained for Cyclin B (D, green), DNA (D, blue), and P-GM130 (E, red). Cyclin B did not localize to the P-GM130-labeled cortical domain (F). (G-I) 0 h GV stage oocyte labeled for PSTAIR (G, green), DNA (G, blue), and P-GM130 (H, red). Spatial overlap of PSTAIR and phosphorylated GM130 staining (yellow) in a cortical domain is evident in the merged image (I). Images are Z-projections of 2 (A-C) or 3 (D-I) consecutive sections; scale bars represent 20 μm in C, F, and I, and 5 μm in C', F', and I'. Arrows indicate the region of the oocyte that is shown enlarged in the insets (A'-I'). Arrowheads denote the position of the GV.
