The Drosophila hnRNP M homolog Rumpelstiltskin regulates nanos mRNA localization.
Anterior-posterior axis patterning of the Drosophila embryo requires Nanos activity selectively in the posterior. This spatial asymmetry of Nanos is generated by the localization of nanos mRNA to the posterior pole of the embryo, where it is subsequently translated. Posterior localization of nanos is mediated by a complex cis-acting localization signal in its 3' untranslated region comprising s...
متن کاملChtop is a component of the dynamic TREX mRNA export complex.
The TREX complex couples nuclear pre-mRNA processing with mRNA export and contains multiple protein components, including Uap56, Alyref, Cip29 and the multi-subunit THO complex. Here, we have identified Chtop as a novel TREX component. We show that both Chtop and Alyref activate the ATPase and RNA helicase activities of Uap56 and that Uap56 functions to recruit both Alyref and Chtop onto mRNA. ...
متن کاملCef1p is a component of the Prp19p-associated complex and essential for pre-mRNA splicing.
The Prp19p protein of the budding yeast Saccharomyces cerevisiae is an essential splicing factor and is associated with the spliceosome during the splicing reaction. We have previously shown that Prp19p is not tightly associated with small nuclear ribonucleoprotein particles but is associated with a protein complex consisting of at least eight protein components. By sequencing components of the...
متن کاملDispensability of nanos mRNA localization for abdominal patterning but not for germ cell development
The development of a functional germline is essential for species propagation. The nanos (nos) gene plays an evolutionarily conserved role in germline development and is also essential for abdominal patterning in Drosophila. A small fraction of nos mRNA is localized to the germ plasm at the posterior pole of the Drosophila embryo, where it becomes incorporated into the germ cells. Germ plasm as...
متن کاملNucleolin is a second component of the CD154 mRNA stability complex that regulates mRNA turnover in activated T cells.
CD154 (CD40L) mRNA turnover is regulated in part at the posttranscriptional level by a protein complex (termed Complex I) that binds to a highly CU-rich region of the 3'UTR. Polypyrimidine tract-binding protein (PTB) has previously been identified as a major RNA-binding protein in Complex I. Nondenaturing gel filtration of total extract from Jurkat T cells demonstrated that the CD154 mRNA-bindi...
