Biochemical and Physiological Mechanisms
EIF2B1 is one of five subunits of eukaryotic translation initiation factor 2B (EIF2B), which is a GTP exchange factor for eukaryotic initiation factor 2 and an essential regulator for protein synthesis. Phosphorylation of eIF2 inhibits GEF activity of EIF

Recombinant Human EIF2B1 Protein (rp192073) - SDS-PAGE
3 μg/lane of Recombinant Human EIF2B1 Protein was resolved with SDS-PAGE under reducing (R) and visualized by Coomassie® Blue staining, showing a band at 30.9 kDa under reducing conditions.
Within the complex, the hexameric regulatory complex resides at the center, with the two heterodimeric catalytic subcomplexes bound on opposite sides (PubMed: 25858979, PubMed: 31048492).
