...-bodies), which are cytoplasmic ribonucleoprotein granules that store translationally repressed mRNA. IP6K1 does not localise to P-bodies, but instead binds to ribosomes, where it interacts with the mRNA decapping complex – the scaffold protein EDC4, activator proteins DCP1A/B, decapping enzyme DCP2...

... formation is not correlated with the sizes of pre-existing RNA processing bodies (P-bodies) but that the two structures often associated rapidly. Immunoelectron microscopy revealed a previously unidentified characteristic of the fine structures of Arabidopsis stress granules and P-bodies: the lack...

.... In this study, we further investigated the cytoplasmic role of MLN51. We show that MLN51 is a new component of processing bodies (P-bodies). When overexpressed, MLN51 localizes in novel small cytoplasmic foci. These contain RNA, show directed movements and are distinct from stress granules and P-bodies...

... mRNA compartmentalization or degradation. Here we report that processing bodies (P-bodies), which are involved in mRNA degradation or storage, are transported to dendrites by conventional kinesin (KIF5A) as a motor protein. Neuronal activation induced by depolarization increased the colocalization of P...

... that the accumulation of newly synthesised partially processed mRNAs results in the formation of foci around the periphery of the nucleus. These nuclear periphery granules (NPGs) contain the full complement of P-body proteins identified in trypanosomes to date, as well as poly(A)-binding protein 2 and the trypanosome...

...J. Ross Buchan; Je-Hyun Yoon; Roy Parker Eukaryotic cells respond to cellular stresses by the inhibition of translation and the accumulation of mRNAs in cytoplasmic RNA–protein (ribonucleoprotein) granules termed stress granules and P-bodies. An unresolved issue is how different stresses affect...

... P-body markers also colocalized with eIF3a. Microscopic analyses of the edc3 Δ lsm4 ΔC mutant demonstrated that different scaffolding proteins are required to induce SGs upon robust heat shock as opposed to glucose deprivation. Even though eIF2α became phosphorylated under these stress conditions...

... the transported ribonucleoparticle (RNP), control mRNA stability and local translation. Recently, the existence of processing bodies (P-bodies), in which mRNA decapping and degradation take place, was revealed in neurons. It was suggested that P-bodies serve as a transient storage compartment for mRNAs, which can...
