General description

Monoclonal Anti-AGO1 (rat IgG2a isotype) is derived from the hybridoma 4B8 produced by the fusion of mouse myeloma cells (P3X63Ag8.653) and splenocytes from rat immunized with a recombinant human AGO1 fusion protein. The Argonaute family of proteins can be subdivided into the Ago subfamily and the Piwi subfamily. Argonaute proteins have a molecular weight of about 100 kDa and are characterized by piwi-argonaute-zwille (PAZ) and PIWI domains. In human, the Ago subfamily consists of hsAgo1−4 (also known as EIF2C1-4). Ago proteins localize to the cytoplasm of somatic cells and are concentrated in cytoplasmic processing bodies. A member of this group, Ago1 is also known to be associated with Golgi and with endoplasmic reticulum. The gene is located on chromosome 1. Eukaryotic initiation factor (EIF2C1)/hAgo1 is expressed in low to medium levels in most tissues, but its expression is particularly high in embryonic kidney and lung.

Immunogen

Biochem/physiol Actions

The Argonaute proteins are evolutionarily conserved between species and have been implicated in both transcriptional and post-transcriptional gene silencing. Eukaryotic initiation factor (EIF2C1)/argonaute 1 plays a vital role in activation of transcriptional enhancers and also regulates alternative splicing in human cells. EIF2C1 levels are also increased in tumors that lack the Wilm′s tumor suppressor gene WT1.The encoded protein interacts with hypoxia-responsive microRNAs (HRMs) and stimulate angiogenic pathway.

The roles of Argonaute proteins in cytoplasmic microRNA and RNAi pathways are well established. However, their implication in small RNA-mediated transcriptional gene silencing in the mammalian cell nucleus is less understood. We have recently shown that intronic siRNAs cause chromatin

MicroRNAs (miRNAs) constitute a class of small non-coding RNAs that regulate gene expression on the level of translation and/or mRNA stability. Mammalian miRNAs associate with members of the Argonaute (Ago) protein family and bind to partially complementary sequences in the
