CGH-1 and the control of maternal mRNAs.
Development requires the translation of stored maternal messenger RNAs (mRNAs) in a spatial and temporally specified manner. Maternal mRNAs are often in large RNA-protein (RNP) granules. Recent papers reveal that maternal mRNA granules in Caenorhabditis elegans oocytes and early development are dynamic and related to P-bodies and stress granules, which are conserved RNP granules seen in somatic cells. In addition, a highly conserved putative RNA helicase, termed CGH-1 in C. elegans, is now shown to be important for both for translation repression and the stability of stored mRNAs. The analysis of CGH-1 ortholog functions in somatic cells and its interacting proteins indicate possible mechanisms by which this protein family might stabilize stored maternal mRNAs.
