Function

edit

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.

Clinical significance

edit

This gene may be critical in the development of ovarian cancer.[7]

Regulation

edit

EEF1A2 is a direct target of miRNA-663 and miRNA-744.[8]
