... fertilization, maternally deposited mRNAs direct biological processes to the point of zygotic genome activation (ZGA). These maternal mRNAs undergo cytoplasmic polyadenylation (CPA), suggesting translational control of their activation. To elucidate the biological role of CPA during embryogenesis, we performed...

... of dorsal-anterior structures and overexpressed organizer-specific genes, indicating that maternal Bicc1 is crucial for normal embryonic patterning of the vertebrate embryo. Bicc1 is an RNA-binding protein with robust translational repression function. Here, we show that the maternal mRNA encoding the cell...

...Douglas W. Houston; Christopher Wylie During the development of Xenopus laevis , maternal mRNAs and proteins stored in the egg direct early patterning events such as the specification of the dorsoventral axis and primary germ layers. In an expression screen to identify maternal factors important...

... provides a suitable and robust approach to study the function of dormant maternal mRNAs. Mos (originally known as c- mos ) and tissue plasminogen activator (tPA, Plat ) mRNAs are dormant maternal mRNAs that are recruited during oocyte maturation; translation of Mos mRNA results in the activation of MAP...

The mechanism by which asymmetry...

...Joan E. Wilson; Joanne E. Connell; Paul M. Macdonald ABSTRACT Although translational regulation of maternal mRNA is important for proper development of the Drosophila embryo, few genes involved in this process have been identified. In this report, we describe the role of aubergine in oskar...
