Clone Host Grade Applications
Monoclonal Rabbit Purified B IH IC FC IF
Eukaryotic initiation factor 2 (eIF2) plays a central role in initiating translation, and provides for a rate-limiting step in protein synthesis. Phosphorylation of a-subunit of eIF2 effectively prevents formation of the eIF2/GTP/Met-tRNAi complex and inhibits global protein synthesis. Three distinct protein kinases regulate protein synthesis in eukaryotic cells by phosphorylating the a-subunit of eIF2 at Serine51. Phosphorylation occurs under a wide variety of different stimuli, including heat shock, serum deprivation, glucose starvation, amino acid starvation, exposure to heavy metal ions, and viral infection.
