General description
GW182 is a phosphorylated cytoplasmic autoantigen. It contains multiple glycine-tryptophan (GW) repeats along with a single RNA recognition motif. GW182 is a protein of 182 kDa, found in mammalian cell types.
Application
Anti-GW182 antibody produced in rabbit has been used as a primary antibody for immunostaining of HeLa cells and human hepatoma cells. It has also been used for indirect immunofluorescence at a working concentration of 2.5-5.0μg/mL using human epithelial HEp-2 cells.
Biochem/physiol Actions
Glycine-tryptophan (GW) bodies or P-bodies are cytoplasmic bodies that are involved in mRNA degradation, storage and translational repression. These bodies contain Argonaute proteins and m-RNAs that associate with GW182. GW182 is involved in post-transcriptional gene silencing/RNA interference (RNAi) via the microRNA pathway. Inhibition of gene expression leads to destruction of GWBs and disruption of RNAi and microRNA-induced gene silencing as it forms an integral component of GWBs.
Physical form
Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

In mammalian cells, proteins involved in mRNA silencing and degradation localize to discrete cytoplasmic foci called processing or P-bodies. Here we show that microscopically visible P-bodies are greatly diminished following West Nile viral infection, but the component proteins are not

MicroRNAs (miRNAs) silence gene expression by binding 3' untranslated regions of target mRNAs. Recent studies suggested silencing is achieved through either recruitment of eIF6, which prevents ribosome assembly, or displacement of eIF4E from the mRNA 5' cap structure. Using Drosophila

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
