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.

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

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

A novel cytoplasmic compartment referred to as GW bodies was initially identified using human autoantibodies to a 182 kDa protein named GW182. GW bodies are small, generally spherical, cytoplasmic domains that vary in number and size in several mammalian cell
