Biochem/physiol Actions: Translation initiation factor eIF-2B subunit Îµ is a protein encoded by the EIF2B5 gene in humans. The eIF2B is composed of five subunits Î±, Î², Î³, Î´ and Îµ, within which the Îµ 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).
Immunogen: synthetic peptide corresponding to amino acids 50-65 of human eIF2epsilon conjugated to KLH. The corresponding sequence is identical in rat and mouse.
Physical form: Solution in 0.01 M phosÂphate buffered saline, pH 7.4, containing 15 mM sodium azide.
Target description: eIF2Bepsilon 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.
