Figure 4. SENP3 is essential for development of Xenopus laevis embryos.

Figure 4

(A) One cell embryos were injected with morpholinos, and subsequently harvested at Stage 39. Equal amounts of protein from Control-MO (left) or SENP3-MO (right) embryos were subjected to SDS-PAGE and Western blotting with anti-SENP3 or -actin antibodies. (B) Samples as in (A) were subjected to SDS-PAGE and Western blotting with anti-SUMO-2 and –SUMO-1 antibodies, as indicated. Note the substantial accumulation of high molecular weight SUMO-2-conjugated species after SENP3 knockdown, while there is essentially no change in SUMO-1 conjugates. (C) Morphological defects of SENP3-MO injected embryos were categorized according to defects in body patterning and eye development, as indicated (lower three panels). The morphology of embryos injected with Control-MO is shown in the upper panel. (D) Quantitation of morphological body deformities of SENP3-MO injected embryos. Bars indicate standard error of the mean values. p values are indicated.
