OverviewNCBI Gene
This gene encodes 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.

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads EEF2 as an antibody target. Whether an autoantibody or antibody against EEF2 could matter depends on whether native EEF2 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
EEF2 is annotated as predominantly intracellular. Intracellular proteins are common autoantibody markers, becoming visible to the immune system after cell injury or altered processing, but are usually markers of disease rather than direct drivers.
Annotation status
The present source text does not explicitly label EEF2 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
