OverviewNCBI Gene
This gene encodes an isoform of the alpha subunit of the elongation factor-1 complex, which is responsible for the enzymatic delivery of aminoacyl tRNAs to the ribosome. This isoform (alpha 2) is expressed in brain, heart and skeletal muscle, and the other isoform (alpha 1) is expressed in brain, placenta, lung, liver, kidney, and pancreas. This gene may be critical in the development of ovarian cancer. [provided by RefSeq, Mar 2014]

Whether an antibody against EEF1A2 can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Protein binding partners of EEF1A2 in the human serome: UniProt-annotated complex subunits plus reported interactors. Each links to its own Seroatlas record.
Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads EEF1A2 as an antibody target. Whether an autoantibody or antibody against EEF1A2 could matter depends on whether native EEF1A2 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
EEF1A2 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 EEF1A2 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
