Beschreibung

General description

eIF2Bε encodes one of five subunits of eukaryotic translation initiation factor 2B (EIF2B), a GTP exchange factor for eukaryotic initiation factor 2 and an essential regulator for protein synthesis.

Immunogen

synthetic peptide corresponding to amino acids 50-65 of human eIF2ε conjugated to KLH. The corresponding sequence is identical in rat and mouse.

Application

Anti-eIF2Bε antibody produced in rabbit is suitable for indirect immunofluorescence (at a dilution of 1:500-1:1,000 using paraformaldehyde fixed NIH-3T3 cells) and western blotting at a dilution of 1:500-1:1,000 using Rat1 or HEK-293T cell lysates.

Biochem/physiol Actions

Translation initiation factor eIF-2B subunit ε is a protein encoded by the EIF2B5 gene in humans. The eIF2B is composed of five subunits α, β, γ, δ and ε, within which the ε subunit is responsible for catalyzing the guanine exchange reaction. Defect in any of these 5 subunits leads to diseases. Mutation in the subunit of eIF2B is associated with an autosomal recessive leukoencephalopathy called Vanishing white matter (VWM).

Physical form

Solution in 0.01 M phos­phate buffered saline, pH 7.4, containing 15 mM sodium azide.
