This complex binds to a 40S ribosomal subunit, followed by mRNA binding to form a 43S preinitiation complex. Junction of the 60S ribosomal subunit to form the 80S initiation complex is preceded by hydrolysis of the GTP bound to eIF-2 and release of an eIF-2-GDP binary complex. In order for eIF-2 to recycle and catalyze another round of initiation, the GDP bound to eIF-2 must exchange with GTP by way of a reaction catalyzed by eIF-2B. This phosphorylation stabilizes the eIF2-GDP-eIF2B complex and inhibits the turnover of eIF2B. Induction of PKR by IFN-γ and TNF-α induces potent phosphorylation of eIF2α at Ser51 Specification Tested Reactivity: human, mouse, rat Cited Reactivity: human, mouse, rat, pig, chicken Host / Isotype: Rabbit / IgG Class: Polyclonal Type: Antibody Immunogen: Peptide Predict reactive species Full Name: eukaryotic translation initiation factor 2, subunit 1 alpha, 35kDa Calculated Molecular Weight: 36 kDa Observed Molecular Weight: 36 kDa GenBank Accession Number: NM_004094 Gene Symbol: EIF2S1 Gene ID (NCBI): 1965 RRID: AB_2881204 Conjugate: Unconjugated Form: Liquid Purification Method: Antigen affinity purification UNIPROT ID: P05198 Storage Buffer: PBS with 0.02% sodium azide and 50% glycerol, pH 7.3.
