General description
Human eukaryotic translation elongation factor 1 alpha has two isoforms, alpha 1 and alpha 2. The alpha 1 isoform gene encodes a subunit of the elongation factor-1 complex which is responsible for the enzymatic delivery of aminoacyl tRNAs to the ribosome. The alpha 1 isoform is expressed in brain, placenta, lung, liver, kidney, and pancreas. The other isoform (alpha 2) is expressed in brain, heart and skeletal muscle.
The alpha 1 isoform is identified as an autoantigen in 66% of patients with Felty syndrome. The gene for the alpha 1 isoform has been found to have multiple copies on many chromosomes, some of which, if not all, represent different pseudogenes. The gene for the alpha 2 may be critical in the development of ovarian cancer.
