Yeast processing bodies and stress granules: self-assembly ribonucleoprotein particles
Processing bodies (PBs) and stress granules (SGs) are two highly conserved cytoplasmic ribonucleoprotein foci that contain translationally repressed mRNAs together with proteins from the mRNA metabolism.

Viruses and the cellular RNA decay machinery. [PDF]
The ability to control cellular and viral gene expression, either globally or selectively, is central to a successful viral infection, and it is also crucial for the host to respond and eradicate pathogens.

HAX-1: A Novel P-Body Protein [PDF]
HAX-1, a multifunctional protein involved in the regulation of apoptosis, cell migration, and calcium homeostasis, binds the 3' untranslated region motifs of specific transcripts. This suggests that HAX-1 plays a role in post-transcriptional regulation, at the level of mRNA stability/transport or translation.

Traffic into silence: endomembranes and post-transcriptional RNA silencing. [PDF]
microRNAs (miRNAs) and small interfering RNAs (siRNAs) are small RNAs that repress gene expression at the post-transcriptional level in plants and animals. Small RNAs guide Argonaute-containing RNA-induced silencing complexes to target RNAs in a sequence-

eIF4E1b is a non-canonical eIF4E protecting maternal dormant mRNAs
Maternal mRNAs are essential for protein synthesis during oogenesis and early embryogenesis. To adapt translation to specific needs during development, maternal mRNAs are translationally repressed by shortening the polyA tails.

ZAP's stress granule localization is correlated with its antiviral activity and induced by virus replication. [PDF]
Cellular antiviral programs encode molecules capable of targeting multiple steps in the virus lifecycle. Zinc-finger antiviral protein (ZAP) is a central and general regulator of antiviral activity that targets pathogen mRNA stability and translation ...

microRNA-Mediated Silencing Inside P Bodies
Cytoplasmic processing bodies, or P-bodies, contain a high concentration of enzymes and factors required for mRNA turnover and translational repression. Recent studies provide evidence that the mRNAs silenced by miRNAs are localized to P-bodies for storage or degradation, perhaps in adjacent subcompartments.

An mRNA decapping mutant deficient in P body assembly limits mRNA stabilization in response to osmotic stress [PDF]
Yeast is exposed to changing environmental conditions and must adapt its genetic program to provide a homeostatic intracellular environment. An important stress for yeast in the wild is high osmolarity.

The decapping activator Edc3 and the Q/N-rich domain of Lsm4 function together to enhance mRNA stability and alter mRNA decay pathway dependence in Saccharomyces cerevisiae [PDF]
The rate and regulation of mRNA decay are major elements in the proper control of gene expression. Edc3 and Lsm4 are two decapping activator proteins that have previously been shown to function in the assembly of RNA granules termed P bodies.
