Localized mRNAs found in specific regions of somatic cells, germ cells, and embryos function through their protein translation products in cell polarization and development. Recent studies on Xenopus and Drosophila eggs and various somatic cells showed that some of the localized noncoding and coding RNAs play a structural (translation independent) role in maintaining the integrity of microtubule and microfilament cytoskeleton and/or may function in protein folding or as a scaffold for the assembly of cytoplasmic complexes essential for egg or embryo development. In addition, structural noncoding RNAs within the cell nucleus have been shown to be involved in the organization of chromatin, nuclear bodies, and DNA replication. The fact that some of the RNAs may have previously unforeseen structural functions, will change our view on traditional functions ofRNAsand will open new frontiers in the field of RNA studies and therapeutic development.
