基本信息
| NACRES | NA.32 |
| General description【一般描述】 | Eukaryotic translation initiation factor 2 subunit 1 α (EIF2S1) is a 35kDa protein. It is the α subunit of the eukaryotic initiation factor 2 (eIF2α). The gene encoding it is localized on human chromosome 14q23.3. |
| Biochem/physiol Actions【生化/生理作用】 | Eukaryotic translation initiation factor 2 subunit 1 α (EIF2S1) catalyzes the first regulated step of protein synthesis initiation and promotes the binding of the initiator tRNA to 40S ribosomal subunits. Binding occurs as a ternary complex of methionyl-tRNA, EIF2, and GTP. The Ser51 in the mature human EIF2-α protein acts as the sole site of phosphorylation that leads to repression of protein synthesis. EIF2-α also plays an essential role in erythropoiesis. |
| Physical form【外形】 | Supplied in 50mM sodium phosphate, pH 7.0, 300mM NaCl, 150mM imidazole, 0.1mM PMSF, 0.25mM DTT, 25% glycerol. |
| Preparation Note【制备说明】 | after opening, aliquot into smaller quantities and store at -70 ℃. Avoid repeating handling and multiple freeze/thaw cycles |
