Purity ~90% (SDS-PAGE). EEF2 is a member of the GTP-binding translation elongation factor family. This protein is an essential factor for protein synthesis. It promotes the GTP-dependent translocation of the nascent protein chain from the A-site to the P-site of the ribosome. This protein is completely inactivated by EF-2 kinase phosporylation. Source: Recombinant protein corresponding to aa574-858 from human EEF2, fused to His-tag at N-terminus, expressed in E.coli. Molecular Weight: ~34.3kD (308aa) Applications: Suitable for use in SDS-PAGE.
