Association of Maternal mRNA and Phosphorylated EIF4EBP1 Variants With the Spindle in Mouse Oocytes: Localized Translational Control Supporting Female Meiosis in Mammals

Abstract excerpt

In contrast to other species, localized maternal mRNAs are not believed to be prominent features of mammalian oocytes. We find by cDNA microarray analysis enrichment for maternal mRNAs encoding spindle and other proteins on the mouse oocyte metaphase II (MII) spindle. We also find that the key translational regulator, EIF4EBP1, undergoes a dynamic and complex spatially regulated pattern of phosphorylation at...
