... 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...

... of posteriorly localized nos mRNA achieves the restricted distribution of Nos protein required to regulate hb and cycB mRNAs in the posterior of the embryo without affecting hb or bcd translation in the anterior. Although some maternal mRNAs, including osk and gurken are translated in the oocyte...

...Christian Sardet; Hiroki Nishida; François Prodon; Kaichiro Sawada Localization of maternal mRNAs in the egg cortex is an essential feature of polarity in embryos of Drosophila , Xenopus and ascidians. In ascidians, maternal mRNAs such as macho 1 , a determinant of primary muscle-cell fate, belong...

... that POS-1 directly binds the glp-1 SCR and suppresses the translation of maternal glp-1 mRNA in the posterior blastomeres. Our preliminary studies using the tri-hybrid system showed that POS-1 interacted with various maternal mRNAs and that a mutant version of POS-1 (2nd C CCH to Y CCH...

... 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...

...Edward P. Robbie; Michael Peterson; Enrique Amaya; Thomas J. Musci ABSTRACT Early frog embryogenesis depends on a maternal pool of mRNA to execute critical intercellular signalling events. FGF receptor-1, which is required for normal development, is stored as a stable, untranslated maternal mRNA...

Synthesis of β 1 -integrin from maternal mRNA is observed throughout the pregastrula phase, though it seems to add only little to the total β...

...Leslie C. Kelso-Winemiller; Matthew M. Winkler The isolation and in vitro assay of maternal mRNPs has led to differing conclusions as to whether maternal mRNAs in sea urchin eggs are in a repressed or ‘masked’ form. To circumvent the problems involved with in vitro approaches, we have used...

...Joel K. Yisraeli; Sergei Sokol; D. A. Melton In an effort to understand how polarity is established in Xenopus oocytes, we have analyzed the process of localization of the maternal mRNA, vg1. In fully grown oocytes, vg1 mRNA is tightly localized at the vegetal cortex. Biochemical fractionation...
