An amino acid sequence from the middle region of human Eukaryotic Translation Initiation Factor 2 subunit 1 (KDEQLESLFQRTAWV) was used as the immunogen for this EIF2A antibody.
Eukaryotic Translation Initiation Factor 2, Subunit 1, also called EIF2-alpha or EIF2A, is a protein that in humans is encoded by the EIF2S1 gene. Hartz(2010) mapped the gene to chromosome 14q23.3 based on an alignment of the EIF2S1 sequence with the genomic sequence (GRCh37). Ernst et al.(1987) stated that protein synthesis is inhibited due to phosphorylation of EIF2S1 in hemin-deprived rabbit reticulocyte lysates. HeLa cells subjected to heat shock, serum deprivation, or interferon treatment followed by virus infection also show a correlation between EIF2S1 phosphorylation and translational repression. Jacob et al.(1989) found that the alpha-Pal transcription factor bound to two palindromic sites within the EIF2S1 promoter and was essential for transcription of the gene.
