Proposed model for granzyme G action during mouse early embryonic development. Maternally produced proteins are abundant in fertilized mouse eggs up to the early 2-cell stage, after which zygotic gene expression increases. Granzyme G, encoding a serine protease, may contribute to this maternal-zygote exchange process. The genes marked with blue color were simultaneously presented in our gene list (Table1) and in the previous report identified by cDNA microarray [49]. See the text for details.
