Fig. 9. PKC-3 and PAR-4 are affected by the depletion of CDC-37 by RNAi. (A,B) Western blots of protein extracts from embryos probed with either anti-PKC-3 antibody (A) or anti-PAR-4 antibody (B). Tubulin was used as a loading control. The upper arrow in B points to a phosphorylated form of PAR-4 that is also reduced in cdc-37(RNAi) embryos.
