RNA granules
Cytoplasmic RNA granules in germ cells (polar and germinal granules), somatic cells (stress granules and processing bodies), and neurons (neuronal granules) have emerged as important players in the posttranscriptional regulation of gene expression. RNA granules contain various ribosomal subunits, translation factors, decay enzymes, helicases, scaffold proteins, and RNA-binding proteins, and the...
متن کاملRNA granules in germ cells.
"Germ granules" are cytoplasmic, nonmembrane-bound organelles unique to germline. Germ granules share components with the P bodies and stress granules of somatic cells, but also contain proteins and RNAs uniquely required for germ cell development. In this review, we focus on recent advances in our understanding of germ granule assembly, dynamics, and function. One hypothesis is that germ granu...
متن کاملTranslocation of RNA granules in living neurons.
Sorting of RNAs to specific subcellular loci occurs in diverse settings from fly oocytes to mammalian neurons. Using the membrane-permeable nucleic acid stain SYTO 14, we directly visualized the translocation of endogenous RNA in living cells. Labeled RNA was distributed nonrandomly as discrete granules in neuronal processes. The labeled granules colocalized with poly(A+) mRNA, with the 60S rib...
متن کاملPlant RNA Regulatory Network and RNA Granules in Virus Infection
Regulation of post-transcriptional gene expression on mRNA level in eukaryotic cells includes translocation, translation, translational repression, storage, mRNA decay, RNA silencing, and nonsense-mediated decay. These processes are associated with various RNA-binding proteins and cytoplasmic ribonucleoprotein complexes many of which are conserved across eukaryotes. Microscopically visible aggr...
