Enables translation elongation factor activity. Acts upstream of or within positive regulation of apoptotic process and translational elongation. Located in cytoplasm. Part of eukaryotic translation elongation factor 1 complex. Is active in synapse. Is expressed in several structures, including central nervous system; eye; genitourinary system; gut; and integumental system. Human ortholog(s) of this gene implicated in autosomal dominant non-syndromic intellectual disability 38; developmental and epileptic encephalopathy 33; and ovarian cancer. Orthologous to human EEF1A2 (eukaryotic translation elongation factor 1 alpha 2). [provided by Alliance of Genome Resources, Apr 2022]
