Summary

GW bodies, also known as mammalian P-bodies, are cytoplasmic foci involved in the post-transcriptional regulation of eukaryotic gene expression. Recently, GW bodies have been linked to RNA interference and demonstrated to be important for short-interfering-RNA- and microRNA-mediated mRNA decay and translational repression. Evidence indicates that both passenger and guide strands of short-interfering RNA duplexes can localize to GW bodies, thereby indicating that RNA-induced silencing complexes may be activated within these cytoplasmic centers. Work over the past few years has significantly increased our understanding of the biology of GW bodies, revealing that they are specialized cell components that spatially regulate mRNA turnover in various biological processes. Formation of GW bodies appears to depend on both specific protein factors and RNA, in particular, microRNA. Here, we propose a working model for GW body assembly in terms of its relationship to RNA interference. In this process, one or more heteromeric protein complexes accumulate in successive steps into larger ribonucleoprotein structures.

There was an error published in J. Cell Sci. 120, 1317-1323.

We apologise for two errors that occurred in the online and pdf versions of this article. The printed version is correct.

On p. 1317, in the Summary, the sentence `Formation of GW bodies appears to depend on both specific protein factors and RNA, in particular, microRNA.' appeared twice. The correct version of the summary is shown below.

On p. 1319, right column, first paragraph, the word order of the penultimate sentence was incorrect and should read:

In particular, studies in Drosophila indicate that GW182 interacts with Ago1 and promotes miRNA-mediated degradation of a subset of mRNA targets (Behm-Ansmant et al., 2006).
