RNA localization.
Messenger RNA (mRNA) molecules are transcribed in the nucleus and then undergo export into the cytoplasm, where they are translated to produce proteins. Some mRNA transcripts do not immediately undergo translation but, instead, are directed to specific areas for local translation or distribution. This produces an asymmetric distribution of cytoplasmic proteins, providing localized activities in...
متن کاملRNA localization in development.
Cytoplasmic RNA localization is an evolutionarily ancient mechanism for producing cellular asymmetries. This review considers RNA localization in the context of animal development. Both mRNAs and non-protein-coding RNAs are localized in Drosophila, Xenopus, ascidian, zebrafish, and echinoderm oocytes and embryos, as well as in a variety of developing and differentiated polarized cells from yeas...
متن کاملRNA localization mechanisms in oocytes.
In many animals, normal development depends on the asymmetric distribution of maternal determinants, including various coding and noncoding RNAs, within the oocyte. The temporal and spatial distribution of localized RNAs is determined by intricate mechanisms that regulate their movement and anchoring. These mechanisms involve cis-acting sequences within the RNA molecules and a multitude of tran...
متن کاملStanding guard: Perinuclear localization of an RNA-dependent RNA polymerase.
S exual reproduction has both potential benefits and potential hazards for the fitness of a genome. The genetic shuffling that accompanies meiosis is recognized as a way of testing genetic variation against environmental changes to select for evolutionary fitness. However, sexual reproduction can also assist the spread of infectious genetic parasites by intermingling two genomes. Meiosis-specif...
متن کاملSpatial regulation of translation through RNA localization
RNA localization is a mechanism to post-transcriptionally regulate gene expression. Eukaryotic organisms ranging from fungi to mammals localize mRNAs to spatially restrict synthesis of specific proteins to distinct regions of the cytoplasm. In this review, we provide a general summary of RNA localization pathways in Saccharomyces cerevisiae, Xenopus, Drosophila and mammalian neurons.
