Outline of Final Research Achievements |
In this study, we try to develop a novel method for protein knockdown. We produced chimeric protein consisting of lysosome binding peptide and protein A. When this fusion proteins were microinjected to zygote with EGFP mRNA and anti-EGFP antibody, EGFP proteins were efficiently degraded. Next, we examined whether this method are applicable to endogenous Stella proteins, a maternal proteins localized in nucleus. However, Stella proteins were not degraded after microinjected with a fusion proteins and anti-Stella antibody. These data suggested that this method is applicable to cytoplasmic proteins, but not to nuclear proteins.
