eIF2Bε Antibody (P-7): sc-9982

eIF2Bε Antibody (P-7) is a mouse monoclonal IgG1 antibody that detects eIF2Bε in mouse and rat samples through applications such as western blotting (WB) and immunoprecipitation (IP). eIF2Bε is a crucial component of the eukaryotic initiation factor 2B complex, which plays a vital role in the regulation of protein synthesis by facilitating the exchange of GDP for GTP on the eIF2 complex. This process is essential for the formation of the eukaryotic initiation complex, which is necessary for the translation of mRNA into proteins. The eIF2B complex consists of five subunits, and while eIF2Bε exhibits guanine nucleotide exchange factor activity on its own, eIF2Bε activity is significantly enhanced in the presence of the other subunits. This cooperative interaction underscores the importance of the entire complex in maintaining efficient protein synthesis, particularly under conditions where eIF2 is phosphorylated, which can inhibit the GEF activity of eIF2B. Understanding the function of eIF2Bε and its interactions within the complex is critical for elucidating the mechanisms of translational control and the cellular response to stress, making anti-eIF2Bε antibody (P-7) an invaluable tool for researchers studying these processes.

The preferred eIF2Bε antibody is eIF2Bε Antibody (B-7): sc-55558.
