Description générale

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.

Actions biochimiques/physiologiques

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.

Forme physique

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

Alcohol use and hepatitis C virus (HCV) infection synergize to cause liver damage, and microRNA-122 (miR-122) appears to play a key role in this process. Argonaute 2 (Ago2), a key component of the RNA-induced silencing complex (RISC), has been shown

In animals, the majority of microRNAs regulate gene expression through the RNA interference (RNAi) machinery without inducing small-interfering RNA (siRNA)-directed mRNA cleavage. Thus, the mechanisms by which microRNAs repress their targets have remained elusive. Recently, Argonaute proteins, which are key
